摘要

本文提出并观察了一种在AMC-V- BLAST(自适应调制编码-垂直-钟-实验室分层时空)组合系统中，每层采用独立MCS(调制编码方案)的系统。此外，与使用通用MCS级别的组合系统相比，该系统应用于独立MCS级别的吞吐量性能得到了很大的提高。仿真结果表明，独立MCS级方案针对不同层的信道条件采用最大吞吐量的调制和编码方案，比普通MCS级方案提高了吞吐量。结果表明，在7~9 dB信噪比范围内，具有独立MCS电平的AMC-V-BLAST组合系统的增益可达700 kbps。

Performance Improvement of the Combined AMC-MIMO Systems with MCS Level Selection Technique

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, the proposed system applied to Independent MCS level shows 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 700 kbps in 7~9 dB SNR (signal-to-noise ratio) range.
