  Abstract

In this paper, we combine AMC (Adaptive Modulation and Coding) with MIMO multiplexing to improve the throughput performance of AMC in Next Generation Communication Mobile Systems. In addition, we propose a system that adopts STD (Selection Transmit Diversity) in the combined system. The received SNR (Signal to Noise Ratio) is improved by adopting STD techniques and an improved SNR increases a probability of selecting MCS (Modulation and Coding Scheme) level that supports higher data rate. The computer simulation is performed in flat Rayleigh fading channel. The results show that the proposed system with 2 transmitter antennas and 2 receiver antennas achieves the gain of 1Mbps at 15dB SNR compared to the AMC-MIMO multiplexing system with the same number of antennas. The adopted STD selects 2 transmission antennas from 4 antennas and MIMO multiplexing process operates with the selected antennas.
