Abstract: 
In this paper, we investigate the performance of a novel diversity combining technique, termed root-mean-square diversity combining (RMSGC), for OFDM transmission over flat Rayleigh fading channels in MIMO systems in the presence of co-channel interference (CCI). Prior published results on BPSK transmission over SIMO channels using ML-detected RMSGC diversity signal showed superior bit error rate performance to classical EGC, SC, SLC diversity combining schemes. In addition, the performance of RMSGC was previously shown to be near-optimal in the sense that it was very close to that of the optimal, but complicated and in many cases non-practical, MRC. While this proved to be a very promising technique for fading channels, it suffered from CCI and its performance deteriorated for more than 8 antennas. In this work, we overcame this drawback and showed that CCI can be resolved using RMSGC-combined and ML-detected OFDM-driven MIMO systems. The performance was further improved using SVM detection, which was also successfully tested in previous work. Novel diversity combining in OFDM-based MIMO systems (PDF Download Available).
