    The prelims comprise: Matrix interpretation of FFT on finite non-Abelian groups Illustrative examples Complexity of the FFT FFT through decision diagrams References

  • An Introduction to Modulations and Waveforms for 5G Networks

    This chapter reviews some of the best recently proposed alternatives to orthogonal frequency division multiplexing (OFDM). It gives mathematical models and block-schemes of the transmitter for all the alternatives considered. The chapter provides a comparative analysis of these modulations, highlights their pros and cons, and discusses their ability to operate in the 5G reference scenarios. It devotes to all major alternative modulation formats beyond OFDM, including filter-bank multicarrier (FBMC), generalized frequency division multiplexing (GFDM), bi-orthogonal frequency division multiplexing (BFDM), universal filtered multicarrier (UFMC) and time-frequency packing (TFP). The chapter deals with the waveform choice issue by providing some shaping pulses that can be considered as alternatives to the rectangular pulse adopted in OFDM. The design of discrete-time windows with the discussed properties is a classical topic that arises in many areas of signal processing, such as fast Fourier transform (FFT)-based spectrum analysis and the synthesis of finite-impulse-response filters with the window method.

  • No title

    This book is Volume III of the series DSP for MATLAB™ and LabVIEW™. 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 (implemented 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. 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 (of which there are more than 200) described in the text and supplied in code form 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™ 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-analo 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 four 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, including 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 Di crete 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 IV, the culmination of the series, 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, Periodic Signal Removal/Prediction/Adaptive Line Enhancement (ALE), Interference Cancellation, Echo Cancellation (with single- and dual-H topologies), and Inverse Filtering/Deconvolution/Equalization.

  • 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.

  • Orthogonal Frequency Division Multiplexing (OFDM)

    Orthogonal Frequency Division Multiplexing (OFDM) is a modulation scheme that converts a high-rate data stream into a number of low-rate streams that are transmitted on parallel subcarriers (tones). A digital implementation of this principle makes use of the inverse Fast Fourier Transform (IFFT). In delay- dispersive channels, intercarrier interference and intersymbol interference can be avoided, or at least mitigated, through a cyclic prefix at the beginning of each OFDM symbol, which converts the linear convolution of the signal with the channel impulse response into a circular convolution, and thus allows single-tap equalization. Coded OFDM allows to exploit the frequency diversity by distributing redundant information over different subcarriers; alternatively spreading information over subcarriers by a spreading sequence results in multicarrier CDMA (MC-CDMA), or (by spreading with an FFT sequence) single-carrier transmission with frequency-domain equalization (SC-FDE). Estimation of the channel transfer function, required for demodulation, is obtained from pilot symbols. By combining least-squares (LS) estimates with knowledge about the channel statistics, linear minimum mean square error (LMMSE) estimates can be obtained. Reduced-rank channel estimation can be obtained through the use of eigenvalue decompositions. A major drawback of OFDM is a high peak-to-average power ratio (PAPR), as it leads to spectral regrowth when nonlinear power amplifiers are used. Methods for its mitigation include coding for PAPR reduction, phase adjustment, and correction by multiplicative or additive functions. Adaptive modulation and coding adjusts the modulation and coding scheme on a particular subcarrier to the channel quality. Optimum power allocation to the subcarriers can be determined from the waterfilling rule. A combination of OFDM with TDMA or FDMA results in Orthogonal Fr equency Division Multiple Access (OFDMA).
