Accuracy improvement of the FFT-based numerical inversion of Laplace transforms

IEE Proceedings - Circuits, Devices and Systems, 2003

The authors present an improvement on the FFT-based numerical inversion of Laplace transforms. Since inversions obtained by the FFT-based method contain large errors, especially for the latter half of the computed region, only the former half is acceptable. The truncation error, which is the greater part of the errors, is analysed and an acceleration method is proposed that uses a ...

  • Accuracy improvement of the FFT-based numerical inversion of Laplace transforms

    The authors present an improvement on the FFT-based numerical inversion of Laplace transforms. Since inversions obtained by the FFT-based method contain large errors, especially for the latter half of the computed region, only the former half is acceptable. The truncation error, which is the greater part of the errors, is analysed and an acceleration method is proposed that uses a property of the complex frequency variable s. This acts as the differential operator in the time domain. The errors are significantly reduced by the proposed method, and thus the inversions become acceptable for almost the entire region

  • A 128∶2048/1536 point FFT hardware implementation with output pruning

    In this work, an FFT architecture supporting variable FFT sizes, 128~2048/1536, is proposed. This implementation is a combination of a 2ppoint Common Factor FFT and a 3 point DFT. Various FFT output pruning techniques for this architecture are discussed in terms of memory and control logic overhead. It is shown that the used Prime Factor FFT as an FFT in the 1536 point FFT is able to increase throughput by exploiting single tone pruning with low control logic overhead. The proposed FFT processor is implemented on a Xilinx Virtex 5 FPGA. It occupies only 3148 LUTs and 612 kb memory in FGPA and calculates 1536 point FFT less than 3092 clock cycles with output pruned settings.

    Nowadays, many applications require simultaneous computation of multiple independent fast Fourier transform (FFT) operations with their outputs in natural order. Therefore, this brief presents a novel pipelined FFT processor for the FFT computation of two independent data streams. The proposed architecture is based on the multipath delay commutator FFT architecture. It has an N/2-point decimation in time FFT and an N/2-point decimation in frequency FFT to process the odd and even samples of two data streams separately. The main feature of the architecture is that the bit reversal operation is performed by the architecture itself, so the outputs are generated in normal order without any dedicated bit reversal circuit. The bit reversal operation is performed by the shift registers in the FFT architecture by interleaving the data. Therefore, the proposed architecture requires a lower number of registers and has high throughput.

  • Low-Power Wideband Analog Channelization Filter Bank Using Passive Polyphase-FFT Techniques

    Polyphase-FFT (P-FFT) techniques allow for low power implementations of high performance multi-channel filter banks by utilizing computation sharing like a standard fast Fourier transform (FFT). Additionally, it enables a longer “effective window length” than is possible in a standard FFT. This characteristic breaks the trade-off between the main-lobe width and the side- lobe amplitudes in normal finite impulse response filters. Thus, P-FFT techniques have been employed for the channelization of wideband input signals in high speed digital communication receivers. In this paper, we present a prototype analog P-FFT based filter bank in discrete time that is used to channelize wideband input signals so as to reduce the speed and dynamic range requirement of the ADCs. The four-channel I/Q prototype is implemented using TSMC's 65 nm GP technology. Based on passive switches, the design operates at high speed, consumes low power, and offers high linearity performance. The measured transfer function shows >38 dB side-lobe suppression at 1 GS/s operation. The average measured IIP3 is +25 dBm differential power and the total integrated output noise is 208 μVrms. The total power consumption for the P-FFT filter bank (eight-channels total) is 34.6 mW (34.6 pJ/conv).

  • Efficient boundary contour mode-matching method of H- and E-plane junctions by fast Fourier transform algorithm

    An efficient boundary contour mode-matching method (BCMM) is applied to the analysis of H- and E-plane junctions with planar and circular boundaries. The proposed approach is based on the use of the fast Fourier transform (FFT) to improve an analytical BCMM method. The electromagnetic field inside the structure is expressed in terms of circular waves, whereas in the rectangular ports a modal expansion is used. Depending on the shape of the contour, the original field expansion is rewritten in plane waves or in other sets of circular waves, replacing the conventional numerical integrations by a new, more suitable procedure. Finally, the transformation between the different expansions is carried out by means of the FFT, increasing notably the efficiency of the method. The presented formulation is verified by comparing simulated results with those obtained by other numerical techniques

  • Design of a configurable fixed-point FFT processor

    In this paper, we focus on the widely-used radix-2<sup>2</sup> Decimation-In- Frequency (DIF) Fast Fourier Transform (FFT) algorithm. A variable-length, controllable-precision FFT processor is proposed. The processor can perform 16, 64, 256 and 1024 point FFT/IFFT and provide flexible wordlength scaling modes for different FFT stages. Thus, the processor is suitable for different precision and FFT length requirements in various applications. Aiming at high throughput performance, single-path delay feedback (SDF) pipeline architecture is adopted. The design is testified on Xilinx Virtex6 xc6vcx240t FPGA. Accordingly, we make a clear comparison between the proposed design and Xilinx FFT v7.1. Our design achieves better signal-to-quantizationnoise ratio (SQNR) property and shorter pipeline latency. Meanwhile, the occupied resource is approximately the same. Moreover, SQNR performance of different FFT length and wordlength scaling modes is analysed.

  • FFT and sparse FFT techniques and applications

    Currently, the FFT is used in different areas, starting from identification of frequency on mechanical vibration to image enhancement. Real-time computation by interpret the acquired data can be easily possible by Fast Fourier Transform (FFT). The best with an efficient algorithm is FFT so it is the foundation for analyzing, monitoring, and controlling various systems. Many applications like digital signal processing, partial differential equation solvers, communications, image processing, all most all Fourier coefficients are very small and known as sparse. In this paper we present different impact of fft and sparse fft in the areas of medical imaging, wireless communication.

  • Pipelined Architectures for Real-Valued FFT and Hermitian-Symmetric IFFT With Real Datapaths

    This brief presents novel parallel pipelined architectures for the computation of the fast Fourier transform (FFT) of real signals and inverse FFT of Hermitian-symmetric signals using only real datapaths. The real FFT structure is transformed by transferring twiddle factors to subsequent stages, such that each stage in the proposed flow graph contains one column of butterfly units and one column of twiddle factor blocks, and each column of the flow graph contains only N samples. This is a key requirement for the design of architectures that are based on only real datapaths. This structure is then mapped to pipelined architectures. The proposed architectures can be used with any FFT size or level of parallelism, which is a power of two. A systematic method to design architectures for FFTs with different levels of parallelism and radix values is presented. By modifying the FFT flow graph for real-valued samples, this methodology leads to architectures with fewer adders, delays, and interconnections.
