为解决单通道通信不能满足卫星通信系统大业务量、高性能的要求及相应系统中通信器件不能满足高速率传输等同题,在研究卫星单通道通信的基础上,提出了多通道通信管理技术和多通道加权轮询算法.仿真结果表明,在星上发射功率无需增大的条件下,多/单通道通信的误比特率及不同信噪比下固定帧长的吞吐量等指标相同,而采用多通道通信管理技术和该算法能够实现卫星通信数据的高速率传输且算法复杂度低,为卫星通信系统的大容量、高速率通信的进一步研究提供了支持.%Multi-channels Communication Management Technology and weighted round scheduler algorithm are proposed to solve the high speed transmission problem that the single channel communication can not accommodate to large traffic and high performance requirements of the satellite communication system as well as does not suit high speed of transmission for the corresponding system equipments of communication. The results show that Multi-channels Communication Management Technology can achieve high speed of the satellite data transmission and the algrithm complexity is low as well as the multi-channels and single cannel communi- cation have the same bit error rate and throughput of fixed length of frame that is fit for different SNR under the condition that the transmission power does not change. The results can provide support for the further study of multi-channels communication for the satellite communication system.
