Limin Cui; Yijun He 2009 IEEE International Geoscience and Remote Sensing Symposium, 2009

Ocean wave parameters, such as significant wave height, can be computed from wave spectrum. Ordinarily X-band nautical radar can produce the three dimensional wave number frequency image spectra from a time series of radar images with a 3-D FFT algorithm. The fundamental image spectrum is related to the surface wave spectrum by the modulation transfer function (MTF). To determine the ...


A harmonic analysis algorithm based on synchronous sampling

Yadong Song; Canmei Yang 2014 IEEE International Conference on Signal Processing, Communications and Computing (ICSPCC), 2014

The harmonic pollution has become a more and more serious problem because of the large-scale application of nonlinear electrical loads in power systems. It is known to all that fast Fourier transformation (FFT) is an effective method for power signal harmonic analysis, but aliasing effect, picket fence effect, spectrum leakage and spectrum disturbance make it suffer from inevitable limitation.

Super-resolution imager via compressive sensing

Qi Wang; Guangming Shi IEEE 10th INTERNATIONAL CONFERENCE ON SIGNAL PROCESSING PROCEEDINGS, 2010

In this paper, we propose a novel imager that can acquire super-resolution (SR) images with significantly fewer sensors. The theoretical basis of this imager is compressive sensing (CS) theory, which calls for a measurement matrix with good properties for effective reconstruction, such as RIP. Such a property indicates that entries of the received signal are effectively aliased. In our imager ...

  • Fourier Transform and Fourier Series

    The Fourier transform (FT) has been widely used in circuit analysis and synthesis, from filter design to signal processing, image reconstruction, and so on. Fourier transform is used for energy signal which contain finite energy. The discrete Fourier transform (DFT) and fast Fourier transform (FFT) are discrete tools to analyze time domain signals. One needs to know the problems caused by discretization and specify the parameters accordingly to avoid nonphysical and nonmathematical results. Mathematically, FT is defined for continuous time signals, and in order to go to frequency domain, the time signal must be observed from an infinite-extend time window. This chapter lists a simple MATLAB code for the Fourier series representation of a given function. The number of terms required in the Fourier series representation depends on the smoothness of the function and the specified accuracy.

  • No title

    This book is Volume IV of the series DSP for MATLAB™ and LabVIEW™. Volume IV is an introductory treatment of LMS Adaptive Filtering and applications, and covers cost functions, performance surfaces, coefficient perturbation to estimate the gradient, the LMS algorithm, response of the LMS algorithm to narrow-band signals, and various topologies such as ANC (Active Noise Cancelling) or system modeling, Noise Cancellation, Interference Cancellation, Echo Cancellation (with single- and dual-H topologies), and Inverse Filtering/Deconvolution. The entire series consists of four volumes that collectively cover basic digital signal processing in a practical and accessible manner, but which nonetheless include all essential foundation mathematics. As the series title implies, the scripts here will run on both MATLAB™ and LabVIEW™. The text for all volumes contains many examples, and many useful computational scripts, augmented by demonstration scripts and LabVIEW&# 482; Virtual Instruments (VIs) that can be run to illustrate various signal processing concepts graphically on the user's computer screen. Volume I consists of four chapters that collectively set forth a brief overview of the field of digital signal processing, useful signals and concepts (including convolution, recursion, difference equations, LTI systems, etc), conversion from the continuous to discrete domain and back (i.e., analog-to-digital and digital-to-analog conversion), aliasing, the Nyquist rate, normalized frequency, sample rate conversion and Mu-law compression, and signal processing principles including correlation, the correlation sequence, the Real DFT, correlation by convolution, matched filtering, simple FIR filters, and simple IIR filters. Chapter 4 of Volume I, in particular, provides an intuitive or "first principle" understanding of how digital filtering and frequency transforms work. Volume II provides detailed coverage of discrete frequency transforms, includi g a brief overview of common frequency transforms, both discrete and continuous, followed by detailed treatments of the Discrete Time Fourier Transform (DTFT), the z-Transform (including definition and properties, the inverse z-transform, frequency response via z-transform, and alternate filter realization topologies including Direct Form, Direct Form Transposed, Cascade Form, Parallel Form, and Lattice Form), and the Discrete Fourier Transform (DFT) (including Discrete Fourier Series, the DFT-IDFT pair, DFT of common signals, bin width, sampling duration, and sample rate, the FFT, the Goertzel Algorithm, Linear, Periodic, and Circular convolution, DFT Leakage, and computation of the Inverse DFT). Volume III covers digital filter design, including the specific topics of FIR design via windowed-ideal-lowpass filter, FIR highpass, bandpass, and bandstop filter design from windowed-ideal lowpass filters, FIR design using the transition- band-optimized Frequency Sampling technique (impleme ted by Inverse-DFT or Cosine/Sine Summation Formulas), design of equiripple FIRs of all standard types including Hilbert Transformers and Differentiators via the Remez Exchange Algorithm, design of Butterworth, Chebyshev (Types I and II), and Elliptic analog prototype lowpass filters, conversion of analog lowpass prototype filters to highpass, bandpass, and bandstop filters, and conversion of analog filters to digital filters using the Impulse Invariance and Bilinear Transform techniques. Certain filter topologies specific to FIRs are also discussed, as are two simple FIR types, the Comb and Moving Average filters.

  • Rigorous Diffraction Theory for 360?? Computer-Generated Holograms

    Most algorithms for a computer-generated hologram using FFT are effective only under the condition that both the input and observation surfaces are finite planes that are parallel to each other. To synthesize a 360 degree hologram in a computer, a numerical simulation of the diffraction on the non planar observation surfaces is required. At first, we propose a simple but rigorous equation which describes the relation between the diffracted wavefront of a 3-D object and its 3-D Fourier spectrum. In this method, an exact solution of the diffraction integral is given by the Green function. This principle gives us an intuitive understanding of calculation processes for various diffraction situation. Alternatively, fast computation solutions for spherical computer generated hologram employing PSF (convolution method) is proposed. We start with Helmholtz equation, with considering a boundary value problem in spherical co-ordinates. The solution define the transfer function and the spectral decomposition of the wave field in the spherical surface. Using the transfer function and the wave spectrum we can develop a spectral propagation formula (for spherical surfaces in spherical coordinates) analogous to the angular spectrum formula. Some computer simulation and experimental results are presented.

  • Near-Ultrasonic Wireless Orthogonal Frequency Division MULTIPLEXING MODEM DESIGN

    This chapter discusses transmission of an image file over a near-ultrasonic (NUS) wireless channel. The image file is orthogonal frequency division multiplexing (OFDM) modulated and transmitted from the speaker of a phone over an NUS wireless channel. The microphone in a PC samples the received signal and demodulates it to restore the image data. The chapter investigates transmit and receive algorithms for NUS OFDM systems. It also analyzes the waveforms and spectra of NUS systems at major processing stages. To demodulate each OFDM symbol, one needs to separately perform fast Fourier transform (FFT) on the properly partitioned portions of rcbb. The vector rcbb is the sampled version of the frequency-offset compensated complex baseband signal. Proper partitioning of rcbb requires locating the starting sample of each OFDM symbol. The chapter is designed to help teach and understand communication systems using a classroom-tested, active learning approach.

  • Circuit Techniques

  • Coherent Train of LFM Pulses

    A train of identical linear-FM pulses provides both range resolution and Doppler resolution, hence its importance and popularity in radar systems. Its ambiguity function still suffers from significant sidelobes, both in delay and Doppler. Thus, modifications are usually applied to reduce these sidelobes. The chapter starts by considering the basic signal without modifications. The 2nd section demonstrates simple implementation (using FFT) of filters matched to higher Doppler shifts. The 3rd and 4th sections describe Doppler sidelobes reduction using interpulse weighting, and range sidelobes reduction using intrapulse weighting. Section 5 presents analytic results of the delay-Doppler response in the presence of both interpulse and intrapulse weighting.
