ABSTRACT: The article introduces an efficient QPSK-DS communication detection method, which advises

to achieve the detection by doing delay-multiply and filtering operation on the received signal directly. Sim-

ulation results show that the proposed method is both effective and robust, and it can meet the low-SNR need

of non-cooperative communication detection. Especially, the implementation of the proposed method does not

need any a priori information, it ...
