摘要：
Decode-and-forward physical layer network coding (PLNC) is one of the promising high-performance techniques for wireless relay networks. This paper studies the limited feedback power control for PLNC. The limited feedback ratios are designed based on the channels' statistical properties. Simulation proves the effectiveness of the proposed scheme. We show that for BPSK modulation, power control with 3 feedback bits can bring a 2 - 3dB gain in terms of SER, and for QPSK modulation power control is only beneficial when it is combined with phase control.
