摘要

近年来，对现代通信设备的研究和对数据服务的需求显著增加。尽管有许多新的调制方案可供选择，但有一个至关重要的要求，即在保持传输带宽和功率的同时，又不失去MIMO系统的质量。本文对用于高性能数字传输的两种先进MIMO调制方案空间调制和正交频分复用进行了分析比较。本研究采用的性能指标是误码率和均方误差，假设正交调幅作为符号映射方案。

Comparative Study of Spatial Modulation and OFDM using QAM Symbol Mapping

The research on modern communication devices and demand for data services are seen increasing predominantly during the recent years. Even though a lot of new modulation schemes are available, there is a vital requirement of a scheme which preserves transmission bandwidth and power without losing the qualities of MIMO systems. This paper deals with the analysis and comparison of two advanced MIMO modulation schemes Spatial Modulation and Orthogonal Frequency Division Multiplexing, adopted for high performance digital transmission. The performance measures employed in this study are Bit Error Rate and Mean Square Error, assuming Quadrature Amplitude Modulation as the symbol mapping scheme.
