The joint maximum likelihood detection (JMLD) in application to non-orthogonal forwarding protocol has higher detection time complexity and poorer detection performance. A new detection method is proposed. The diversity gain of strong signal frame is obtained by maximal ratio combining and detected in advance. The detection result is thereafter used to eliminate interference to weak signal frame. At last, the weak signal frame is detected. Analysis and simulation show that, comparing with JMLD, the proposed method reduces the detection time complexity effectively and improves the bit error performance. The bit error rate of analysis and simulation value tends to be consistent at high signal-to-noise ratio.
