摘要

Ka波段再生载荷为GSAT-4卫星的转发器[1]。它提供了窄点波束、宽带宽和小尺寸的天线，用于发射和接收。信号解调器是再生载荷的重要子系统之一。这种信令解调器是内部开发的，用于提供信令信息，以提供一个点波束到另一个点波束之间的通信。为了实现从用户终端获取信令请求并对请求进行板载处理的功能，开发了解调器软件。

Design, implementation and realization of 64Kbps QPSK based burst demodulator for onboard application

The Ka band regenerative payload is a transponder of GSAT-4 satellite [1]. It provides Narrow Spot Beams, Wide Bandwidth and small size of antenna for both transmission and reception. The Signaling Demodulator is a one of the important subsystem of regenerative Payload. This Signaling Demodulator was developed in-house for providing signaling information to provide communication between one spot beam to other. The demodulator software was developed for functionality of getting the signaling request from the user terminal & the processing of the request onboard.
