This paper proposes a new combinational technology which is feasible to apply physical-layer network coding (PNC) to wireless fading channel by employing the harmful interference strategically. The key step of PNC is that terminals embrace interference and recover original signals from the intervening signals. Generally, the signals from different sources are mutual independent. We exploit an enhanced Joint Diagonalization Separation named Altering Row Diagonalization (ARD) algorithm to maximize the cost function measuring independence, by which we can separate these independent signals by blind separation method without any priori information about channel in wireless fading environments. In conclusion, the proposed method APNC (ARD PNC) performs well in PNC with higher bandwidth utility and lower error rate.
