This paper presents a joint physical-layer network coding (PNC) and serially concatenated continuous phase modulation (SCCPM) scheme in a two-way relay (TWR) channel. This proposed scheme can be viewed as a serial concatenated codes (SCCs) scheme in which the joint CPM and PNC is the inner code and the convolutional code (CC) is the outer code. It aims to improve the spectral efficiency, error performance...
Physical-layer network coding (PNC) has obtained much attention due to its ability to improve throughput in relay-aided communications. In this paper, we introduce orthogonal frequency division multiplexing-continuous phase modulation (OFDM-CPM) signals into a two-way relay (TWR) channel adopting the PNC protocol to form a new scheme. With PNC, the TWR communication is performed during two phases...
