| 摘 要： | 以卫星通信系统中的高速调制为背景，研究了有限带宽下实现高速信息传输所选用的各种高阶调制方式。国内外常见的调制方式有多进制相移键控（MPSK）、多进制正交振幅调制（MQAM）和多进制幅度相移键控（MAPSK）等3种方式，分别从最小欧式空间距离、误码率性能和恒包络特性等方面对这3种调制方式进行了对比，分析了其优、缺点，分别给出了3种调制方式的适用范围和场合。

| Abstract: | On the background of a high-speed modulation project in satellite communication systems, various high-order modulation modes with limited bandwidth for high-speed satellite communication systems were studied. The general modulation modes at home and abroad mainly include MPSK （Phase Shift Keying）, MQAM （quadrature amplitude modulation） and MAPSK （amplitude phase shift keying）. These modulation modes were compared and analyzed in the respects of the least Euclidean distance, the performance of BER （bit error rate） and the constant envelope characteristics. Finally, the applicable scopes of the three modulation modes were respectively presented by comparing their advantages and disadvantages. |
