摘要

研究了具有M个发射天线、N个接收天线、R个中继节点和独立瑞利衰落的多天线(MIMO)系统的分集复用增益权衡问题，其中中继采用分布式空时码。在这种两阶段方案中，这种权衡与具有R个发射天线和min{M,N}个接收天线的MIMO系统的权衡一致。

Diversity-Multiplexing Gain Trade-off of a MIMO System with Relays

We find the diversity-multiplexing gain trade-off of a multiple-antenna (MIMO) system with M transmit antennas, N receive antennas, R relay nodes, and with independent Rayleigh fading, in which the relays apply a distributed space-time code. In this two-stage scheme the trade-off is shown to coincide with that of a MIMO system with R transmit and min{M,N} receive antennas.
