Phase Rotation and Link Selection Methods for DSTTD-Based Two-Path Relay Systems
Jingon Joung, Sumei Sun · IEEE Communications Letters · 2011
Phase rotation and link selection methods are proposed to increase the post-processing signal-to-noise ratio of two-path relay system, in which source and two relays transmit 2-by-2 space-time block coded (STBC) signals. Computer simulation verifies that the proposed methods can provide significant performance enhancement over a naive two-path relay system.
