A Reception Technology Based on Adaptive Channelization Designed for Time-varying and Uniform Distributing Signal

The problem of existing several sub-band signals in the receiver bandwidth is often faced with in the non-cooperation situation. Meanwhile, the bandwidth, location and number of the signals are unknown to receiver, and the signals are often time-varying in the modern electronic warfare. For this situation, An adaptive channelization technology of filter-banks, which is designed for time-varying and uniform distributing signal, is proposed and confirmed in the processing platform. By means of designing a dynamic channelized IP core, receiving signal without blind-zone, Spectrum splicing, parameter estimation and the receiver’s offsets correction, the IF signals can be channelized received in the absence of priori information. Experiments show that the program can effectively overcome the effects of frequency offset and other unknown factors, and makes center frequencies of output signals align to 0 frequency accurately. Finally the unattended channelized receiver is achieved.
