Channel quantization-based physical-layer network coding for two-way relay STBC system

This paper considers a two-hop two-way relay system which uses the Alamouti space-time code for signaling between all nodes and channel quantization for PNC mapping at the relay. Specifically, based on the concept of CQ-PNC we derive a PNC mapping rule for two pairs of network coded symbols. | Channel quantization-based physical-layer network coding for two-way relay STBC system
