GSE封装格式在DVB系统中的应用

Application of GSE format in DVB system

DVB系统在卫星通信领域应用广泛,本文基于第二代DVB-S2(DVB-S2X)标准协议,研究了GSE封装数据包长度对DVB系统传输效率的影响,并仿真出系统性能最优的GSE长度值;依据GSE最优值设计了50MSPS符号速率DVB-S2链路的超帧结构,实现了各类型信令/业务数据混合传输、延迟时间恒定、数据速率恒定的传输系统,增大了带宽利用率和数据吞吐量,带来了经济效益。

DVB system is widely used in the field of satellite communication.Based on the second generation DVB-S2(DVB-S2X)standard,this paper studies the effect of packet length of GSE package on the transmission efficiency of DVB system,and simulates the GSE length value with the best system performance;The superframe structure of 50MSPS DVB-S2 forward-link is designed according to GSE optimum value,and the DVB system with mixed transmission of signaling and traffic,constant delay time and data rate is realized,which enhances bandwidth utilization and data throughput,and brings economic benefits.
