Abstract
In this paper, we combine Adaptive Modulation and Coding (AMC) with Transmit Diversity (TD) to improve the performance of AMC in CDMA systems. An improved SNR increases a probability of selecting Modulation and Coding Scheme (MCS) level that supports higher data transfer rate. Therefore, higher average throughput can be achieved. As an open-loop TD, Space-Time block coding based Transmit antenna Diversity (STTD) is applied to AMC. For a closed-loop TD, Selection Transmit Diversity (STD) is combined with AMC. The results show that higher throughput is achieved by AMC-TD schemes. Compared to the conventional AMC, AMC-STTD scheme shows about 250kbps increase in throughput. In addition, AMC-STD with two transmit antennas achieves about 420kbps throughput improvement over the conventional AMC at 9dB SNR in flat Rayleigh fading channel.
