      다국어 초록 (Multilingual Abstract) kakao i 다국어 번역

      In this paper, we propose and observe a system that adopts Independent MCS (Modulation and Coding Scheme) level for each layer in the combined AMC-V-BLAST (Adaptive Modulation and Coding-Vertical-Bell-lab Layered Space-Time) system. Also, comparing with the combined system using Common MCS level, we observe how much throughput performance is improved. As a result of simulation, Independent MCS level case adapts modulation and coding scheme for maximum throughput to each channel condition in separate layer, resulting in improved throughput compared to Common MCS level case. Especially, the results show that the combined AMC-V-BLAST system with Independent MCS level achieves a gain of 700kbps in 7-9dB SNR (Signal-to-Noise Ratio) range.
