摘要：
stationary signal analysis. Many algorithms to compute the discrete Wigner-Ville distribution (DWVD) have been proposed. New efficient methods for computing the discrete Wigner-Ville distribution are presented. Observing that the DWVD is real and periodic, it is possible to express it as the DFT of a complex conjugate sequence of reduced length. Comparison to other algorithms are also made. © 1990, The Institution of Electrical Engineers. All rights reserved.
