| 摘 要： | 射频干扰会严重影响卫星通信链路性能,而自适应调零天线是一种有效的卫星抗干扰措施.本文对应用于多波束天线的各种自适应波束形成算法进行对比分析,理论分析与仿真结果皆表明,DMI和RLS算法相对经典的LMS算法而言,在收敛速率和输出信噪干扰比上皆有相当的优越性.这些快速算法适合卫星通信的干扰抑制应用.

| Abstract: | Radio frequency interference will cause severe degradation on satellite communications link performance,and adaptive nulling antenna is an effective anti jamming measure for communication satellite.This paper presents a comparative analysis of various adaptive beamforming schemes when used with multiple beam antennas.The results of analysis and simulation show that both DMI and RLS algorithms offer the advantages of faster convergence rates and better SINR performance over simple LMS algorithm.These fast algorithms are quite proper to cope with undesired interference signals in an operational satellite communication environment. |

| Keywords: | adaptive beamforming adaptive algorithm communication satellite multiple beam antenna radio frequency interference |
