Improvement of the throughput-SNR trade-off using a 4G adaptive MCM system
Wireless Information Technology and Systems（2010）
Abstract
The MIMO-OFDM Adaptive MCM System changes MIMO scheme, channel coding rate, and modulation scheme, adaptively, according to the channel conditions. And the addition of Pre-coding and Antenna Subset Selection assures a better performance and higher data rate. The MIMO-OFDM Adaptive MCM System achieves a better average throughput performance than a Non Adaptive-MCM system; as SNR increases, the throughput increases almost linearly. Based on the simulation results, we conclude that the proposed MIMO-OFDM Adaptive MCM System represents a feasible solution for improving the throughput-SNR tradeoff in the next generation of mobile communication systems.
