The uniform channelized wideband digital receiver with 50% coverage is proposed and realized according to the multiterm filter set theory and FFT method.It is mainly applied to the realization of software radio and electronic warfare.The entire sampling band is divided into several parallel channels,which makes the signal intercepted all probability,and is the ideal front-end receiver in investigating the hopping frequency signal and adaptive communication signal.The principle of channelized wideband digital receiver,software simulation and hardware implementation are elaborated.The algorithm,procedures and hardware platform for practical engineering are designed.The 8 chanel digital reception in the frequency range of 0~100 MHz is achieved.
