Research on Total Probability Digital Channelization Technique Without Blind Zone

Based on the problems of blind zone and overlap in the traditional digital channelization model, it is hard to meet the requirements of total probability detection in modern electronic reconnaissance receiver. The paper proposes a kind of overlapping digital channelization model, the processed signal is joint together seamlessly in frequency domain, making the detection of cross channelization signal possible. The proposed algorithm is simulated and tested by actual data sampled by AD, the results validate high efficiency of the proposed algorithm, and it can be applied in the situation of total probability detection for non-cooperation signal receiving.
