| 摘 要： | 提出了采用自适应的NDLMS(归一化去相关最小均方误差算法)解调DPSK(差分相移键控)调制信号的方法,并利用SystemView仿真工具对解调性能进行了分析。针对小信噪比下门限失效的问题,利用误差信号来改进门限判决的质量。仿真表明采用自适应算法解调性能良好,且易于数字实现。

| Abstract: | This paper presents a method of DPSK signal demodulation by NDLMS adaptive algorithm, and analyzes its performance by System View. By using the error signals to reduce the demodulated signals, the performance of adjudgement will be better when the SNR is low. It is indicated by simulation experiments that this method of demodulation has good performance and it is easy to realize by digital signal processing technology. |
