In order to obtain lower SNR estimation, spectrum accumulation average technique ( AAT) and cross-correlation accumulation technique ( CCAT) are added to the output of CDM processing, several improved methods are proposed, and obtain lower SNR limitation effectively. 为获得更低的信噪比容限,提出了在平方倍频处理后端加入频谱集平均技术和互相关积累技术的若干改进方法,成功实现更低信噪比下的估计。
