摘　　要：针对机载超短波话音通信系统中通信话音丢失的问题,将等增益合并技术应用到机载超短波话音通信系统中,并结合实时时延估计技术和buffer缓冲时延补偿技术,提出一种实时等增益合并算法。仿真结果表明,该算法根据不同信道间信息的互补来增强接收效果,改善机载话音通信系统中通信话音丢失的问题,有助于提升机载超短波话音通信的稳定性和可靠性。The information of communication speech may be lost in the airborne ultra-short wave radio speech communication system,a real-time equal gain combining algorithm is proposed to solve the problem,which applies the equal gain combining algorithm in the airborne ultra-short wave radio speech communication system combining the real-time time delay estimation technology and buffering time delay compensation technology. The results of simulation indicate that this algorithm can improve the reception by using the compensation of information from different channel,which improves the problem that the information of communication speech may be lost in the airborne ultra-short wave radio speech communication system and is helpfulto improve the stability and reliability of the airborne ultra-short wave radio speech communication system.
