Design of Satellite Communication Channel Monitoring Sequence Length

In satellite communication system, the quality of channel affects the communication performance of system directly. According to the characteristics of satellite communication, the length of satellite communication channel monitoring sequence is designed. The design of the length can not only meet requirement of the satellite communication channel quality monitoring, but also the need of capture probability and capture time of the receiver to the monitoring sequence, which avoids the influence of low capture or long delay on the channel real-time monitoring. In order to solve the poor quality of satellite communication channel, we design the length of the monitoring sequence in the case of high error, and the error analysis of CSI (channel state information) is carried out and capture probability and capture time of monitoring sequence is analyzed in this paper. The effectiveness of the proposed method is verified by simulation.
