摘　　要：针对受强高斯白噪声污损的DS/BPSK信号载频估计问题,在研究平方倍频法的基础上,借鉴相关积累思想,提出了两种改进方法,有效地降低了估计时所需要信号的信噪比容限或系统设备量。计算机仿真结果验证了改进方法的有效性。For the issue of cartier frequency estimation of DS/BPSK signal damaged by strong AWGN, based on the research of nonlinear method, profited from the correlation accumulation thought, two improved methods were proposed in this paper. The sirrmlation result shows that these proposed methods will reduce SNR limitation or system burthen successfully and effectively.
