FPGA-based simulation and design of parallel algorithm for multirate-based discrete Gabor transform
Rui Li, Liang Tao · Computer Engineering and Applications Journal · 2011
Gabor transform has been recognized as a very effective method of time-frequency analysis in signal processing.However,the real-time applications of the Gabor transform are limited because of the high computational complexity.Thus,the multirate filtering-based discrete Gabor transform is recently proposed to solve the problem.This paper discusses the use of FPGA to implement the multirate filtering-based discrete Gabor transform.Quartus II 9.0,Modelsim and Verilog hardware description language will be used to simulate and design the multirate filterbank for the discrete Gabor transform.
