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
