SOQPSK相关技术研究

A Research on SOQPSK Technics

介绍了整形交错正交相移键控(SOQPSK)的基本原理,同时基于Laurent分解原理,对全响应的整形交错正交相移键控(SOQPSK-MIL)信号进行了分解,并给出了基于分解后信号的简化相干接收机模型,并通过计算机进行仿真,得到其误码性能曲线,性能几乎没有损失。

In this paper, it gives a detailed keystone of shaped offset quadrature shift keying technics and analyzes the process of Laurent decomposition. Also, it applies the method of Laurent decomposition to decompose the full-response SOQPSK signal and derive its＇ expression. Based on the expression, a simplified coherent model of the receiver is proposed, the curve of bit error rate is derived after the computer simulation. And the performance seems to have no loss.
