The short-time Fourier transform(STFT) algorithm is an easy and efficient method for digital channelized reception with limitation in the operation speed of DSP. The method based on extend resources with parallelism pipeline architecture for high speed is supposed in this paper to realize transport data at a low speed and make efficient use of hardware.Detection and estimate parameters of signal in real-time are also realized. The method is suitable for hardware implementation at a high speed.

Key words: STFT, digital channelized receiver, parallelism pipeline architecture, parameter estimation
