| Abstract: | For the non-cooperative detection of the DSSS/QPSK communication,the paper proposes a time-domain-processing-based method for the detection of DSSS/QPSK signals.The proposed method,starting with the basic structure character of the DSSS/QPSK signals,achieves the detection of DSSS/QPSK signals and the estimation of the information symbol period by doing delay-multiply,correlation on the received signals.The computer simulations show that the proposed method is feasible and efficient,and the proposal & its application have a certain referential importance for the non-cooperative detection of the DSSS/QPSK communication. |
