Performance analysis of the DS/SS communications receiver implementing a short time Fourier transform excision system
The short-time Fourier transform (STFT) is employed for nonstationary jammer excision in direct sequence spread spectrum (DS/SS) communication systems. The received signal is first analyzed by the STFT. The localized interferers in the time-frequency (t-f) domain are then removed by binary excisions...
