Abstract

Abstract: Serially concatenated continuous phase modulation (SCCPM) is bandwidth and power efficient in point-to-point communication systems. The physical-layer network coding (PNC) protocol propsed in 2006 can boost the throughput of a two-way relay channel (TWRC). In this paper, we integrate SCCPM with bit interleavers into PNC, i.e., SCCPM-PNC, which inherits the advantages of the both, in wireless TWRC. The decoding structure of the relay for the superimposed SCCPM signals is designed. Furthermore, the influences of various parameters such as the constraint length of convolutional code (CC), the interleaver size and the number of iterations, on the performance of SCCPM-PNC are simulated and discussed.
