| 摘 要： | Nakagami信道是一种适应性较强的信道模型，MQAM(M-ary quadrature amplitude modulation)是一种频谱利用率较高的调制方式。在存在多径影响的无线通信环境中，最大比合并(maximum ratio combining)方式的分集接收是克服衰落的有效方法。本文利用适用范围更广的Nakagami信道模型，在多径衰落的情况下对最大比合并分集接收的MQAM系统误符号率性能作了分析。仿真结果对分析实际信道下具体系统的性能具有一定的参考价值。

| Abstract: | Nakagami channel is a channel model with great flexibility and MQAM (M-ary quadrature amplitude modulation) has a highly frequency efficiency. Under the multi-path environments, MRC (maximum ratio combing) is an effective technique to overcome the signal fading. This paper focuses on the SER performance of the system by using MRC in the Nakagami channel under the multi-path environments. The result of the simulation will be a reference in practical performance analysis. |
