摘要
ASLC系统中通道间频率特性失配使主、辅通道信号产生去相关作用,导致对消性能大大下降. 在通道中插入FIR均衡器,可以补偿各通道之间的失配.计算机仿真表明,通道均衡技术可以使对消比有较 大幅度的提高.
In the adaptive side-lobe cancellation (ASLC) system, the frequency mismatch between channels results in de-correlation between the main channel and auxiliary one, which makes the cancellation performance degrade greatly. By inserting the FIR equalizer, the mismatch between various channels can be compensated. By computer simulation, it shows that the channel equalizing scheme can be used for improving the cancellation ratio effectively.
