Design and Implementation of 2.4Gsps Digital Channelized Receiver

The digital channelized receiver is an efficient way to deal with the problem how to receive signals arriving simultaneously in electronic reconnaissance receiver[1]. An Wideband digital channelized receiver based on weighted overlap-add (WOLA) filterbanks structure is derived from polyphase discrete Fourier transform (PDFT) filter digital channelized receiver. Adaptive double threshold detection method is apply to channel signal detection. Simulation result of the channelized receiver is given. A wideband digital channelized receiver has 2.4Gsps sampling rate and 64 channels channelized with the hardware platform consists of high speed analog-digital converter and high performance field programmable gate arrays. The results show that the design is available and effective.
