摘要
在短波通信中针对盲信道个数不恒定、信道频谱理论上不重叠的盲信道分离问题,基于小波多分辨率分析技术提出一种盲信道快速分离算法,并对实测短波通信信号进行盲信道快速分离的Monte Carlo试验。仿真结果表明,本文所提出的短波盲信道快速分析算法的分离精度和信道正确分离率都较高、抗噪声干扰能力强。
Consider blind channel separation of SW communication on condition that the number of blind channels is not deterministic, and channel frequency band is not overlapped with each other theoretically. A fast blind channel separation algorithm of SW communication is proposed based on wavelet multiresolution analysis. By using the proposed fast blind channel separation algorithm, Monte Carlo simulation experiment of blind channel separation in SW communication has been done. Simulation results show that the proposed blind channel algorithm is of high separation precision, high right separation rate and stronger anti-noise-interference ability.
