Real-Valued Discrete Gabor Transform of Linear Time-Varying Systems: Exact Representation and Approximation
Bin Luo · 中国电子科技：英文版 · 2005
An efficient algorithm for the representation and approximation of linear time-varying systems is presented via the fast real-valued discrete Gabor transform. Compared with the existing algorithm based on the traditional complex-valued discrete Gabor transform, the proposed algorithm runs faster, can more easily be implemented in software or hardware, and leads to a more compact representation. Simulation results are given for demonstration.
