A TDD IDMA Downlink With MRC Pre-Equalization
Pei Lin, Guangxi Zhu, Remi Tassing, Xiaodong Zhu · 2008
It is shown in the paper that by employing a maximum ratio combining (MRC) pre-equalizer, the complexity of the receiver in an Interleave-Division Multiple-Access (IDMA) downlink is reduced, while similar or even slightly better performance is achieved, compared to that using Log Likelihood Ratio Combining (LLRC).
