摘要
短波信道中存在大量突发的、断续的干扰,严重影响了通信的可靠性。对自适应多门限算法抑制窄带断续干扰的性能进行了分析,针对该算法抑制窄带断续干扰能力差的缺点,提出了一种改进算法,并进行了理论分析和性能仿真。仿真结果表明此算法可明显改善误码率性能。
A great deal of gusty and discontinuous interference exist in shortwave communication channel, and depress greatly the dependability of communication. The performance of adaptive multi-threshold algorithm in discontinuous narrowband interference suppression is analyzed, and a improved scheme is proposed to overcome the shortcoming of the algorithm. The simulation results show that the new scheme can improve the performance of error-rate.
