摘要：

为改善极化信号接收质量，遥测接收系统通常采用极化分集合成方案。而大部分方案采用多锁相环分集接收结构，电路相对复杂，实现较困难。本文提出一种单锁相环最大比极化分集合成接收电路，仿真表明该电路有效可靠、结构简单，具有较好的工程应用价值，并已通过FPGA实现应用于工程中。

Abstract:

In order to improve the acquisition quality of polarization signal，the telemetry receiving systems usually use the polarization diversity-synthesized scheme. And most of them are multi-PLL diversity receiving structure which is complex and hard-realizing. This paper presents a single-PLL maximal-ratio polarization diversity-synthesized receiving circle. The simulation shows the circle which has great application value in project is simple in structure and easy to implement. And it’s already applied in a project on FPGA.

Key words: PLL, polarization diversity-synthesized, maximal-ratio, FPGA
