基于矢量天线的新型三维调制解调方法

摘要

借助于矢量天线，提出了一种将信号相位、极化幅度与极化俯仰角参数进行三维调制的方法。给出了极化与相位联合三维调制解调的实现策略，讨论了三维联合调制的星座图和星座点分布方案。推导出了三维联合调制信号误码率的解析表达式并进行了仿真。分析与仿真结果均表明：提出的调制方法具有传输速率高和误码率低的特点。%Based on vector antenna, a novel approach to the three-dimensional joint modulation of the phase, polarization amplitude, and polarization angle parameters of an electromagnetic signal is presented. Its implementation strategy is also given while the proposed three-dimensional joint modulation constellations and the con- stellation point distributions are discussed. The calculation method of the bit error rate（BER） of the proposed three-dimensional joint modulator and demodulator is also given. Both the analysis and the simulation results show that a high informa- tion transmission rate can he kept while a low hit error rate is obtained by the pro- posed method.
