多再生中继系统中基于多播线性收发机辅助的多流多播策略
Multicast-aware linear transceiver-aided multi-stream multicast scheme in multiple regenerative relay systems
摘要
Abstract
For multiple regenerative relay systems,we propose a multicast-aware linear transceiveraided multi-stream multicast scheme to improve the system capacity when it is limited by relay-todestination link.In this scheme,joint transmission of data-sharing relays is employed to improve the weak relay-to-destination link.To efficiently distribute the needed sharing data to relays,multistream multicasting is performed in source-to-relay link and we design a multicast-aware linear transceiver which intelligently collects same streams and separates different streams.The simulation results show that system capacity is effectively enhanced,especially for weak relay-to-destination link.关键词
