Abstract
In this paper, we propose a Double-Space Time Transmit Diversity (D-STTD) communication system with Adaptive Modulation and Coding (AMC) scheme and analyze its performance using simulation experiments. The simulation results show that the probability of selecting a high Modulation and Coding Scheme (MCS) level increased as the Signal to Noise Ratio (SNR) improved. Furthermore, the D-STTD communication system with AMC scheme provided a more uniform throughput distribution throughout the entire SNR range compared to its counterpart which did not apply AMC scheme. Also, the maximum throughput of the D-STTD communication system with AMC scheme was twice that of a conventional AMC communication system or a Space Time Transmit Diversity (STTD) communication system with AMC scheme.
Highlights
With the rapidly increasing demand for high-speed data transmission, next-generation mobile communication is expected to adopt a number of new technologies, including AMC, Orthogonal Frequency Division Multiplexing (OFDM), Multiple Input Multiple Output (MIMO), and Hybrid-Automatic Repeat Request (H-ARQ).The AMC scheme varies the coding rate and modulation scheme according to the channel status to improve its transmission rate and has been employed in various high-speed wireless communication applications including Wireless Broadband (Wibro) Internet and High Speed Downlink Packet Access (HSDPA)

Summary
With the rapidly increasing demand for high-speed data transmission, next-generation mobile communication is expected to adopt a number of new technologies, including AMC, Orthogonal Frequency Division Multiplexing (OFDM), Multiple Input Multiple Output (MIMO), and Hybrid-Automatic Repeat Request (H-ARQ). The AMC scheme varies the coding rate and modulation scheme according to the channel status to improve its transmission rate and has been employed in various high-speed wireless communication applications including Wireless Broadband (Wibro) Internet and High Speed Downlink Packet Access (HSDPA). Through continued technical developments, it is expected to be adopted by numerous wireless communication standards of the future. The D-STTD scheme complements the conventional STTD scheme in terms of throughput and its use is being widely discussed regarding various wireless communication standards
