RCS信道快速载波同步设计
Design of fast carrier synchronization in RCS channel
摘要
Abstract
RCS channel,which has many characteristics,such as multi-user,high clock synchronization requirement and short frame length,needs rapid carrier synchronization. The unique-words(UW)are designed in data frame to realize fast carrier synchronization of RCS channel. A carrier synchronization scheme,which is easy to realize,was designed in combination with carrier synchronization algorithm based on UW and twice-phase-estimation method based on Viterbi-Viterbi algorithm. The perfor-mance of this design was proved by Matlab simulation. The design scheme can realize phase synchronization rapidly,and has been applied successfully to a satellite transceiver.关键词
