The wide-band digital channelized receiver characterized by anti-aliasing and with no blind-zone is discussed in this paper.In order to solve the problem that the two real channels of two end-zone spectrum for wide-band digital channelized receiver based on even-arrangement cannot be directly employed for signal detection,Hilbert transformation is adopted to transform the two real channels into two plural channels.All channels,including real channels transformed by Hilbert and plural channels,are processed by signal detection and estimation.So two end-zone spectrum utilization problem is solved and spectrum bandwidth coverage is expanded for wide-band digital channelized receiver.The simulation experiments show that the proposed algorithm is feasible and effective.
