摘要

随着天地一体化信息网络的建设，卫星直连手机终端逐步普及。如何在卫星链路资源受限的情况下实现稳定清晰的语音通信，成为卫星语音通信业务发展的核心挑战。由于卫星信道具有带宽受限、路径损耗大、时延高等特点，地面蜂窝网络的语音编码难以直接适用，低速率语音编码技术是实现卫星语音服务的关键。基于此，系统总结了面向卫星通信的低速率语音编码技术，介绍了主流技术路线的原理、特点及性能评估，分析各方法的优缺点，并展望未来研究方向。

Abstract

With the advancement of the space-integrated-ground network

device-to-satellite communication is transitioning from concept to reality. Achieving stable and clear voice communication with limited satellite link resources is a key challenge for the industry. Due to the bandwidth limitations

high path loss

and high transmission delays of satellite channels

speech codecs used in terrestrial networks are not directly adaptable to satellite communication scenarios. Therefore

low bit-rate speech codec is crucial for satellite voice services. Based on this

the low bit-rate speech codec technologies for satellite communication were systematically summarized

the principles

characteristics

and performance evaluations of mainstream technical routes were introduced

the advantages and disadvantages of each method were analyzed

and future research directions were prospected.
