本文由最佳估计的观点对时频相编码分集信号最佳解调器进行了方案设计。文中分析推导了白(或非白)加性高斯噪声下最大似然估计的关系式;进而研究了白(或非白)加性高斯噪声下,末知相位的二进制OOK,PSK信号最佳幅度估计的各关系式并理定了最佳估计器方案。本文从几个方面的分析证明了此一估计的最佳性,唯一性。给出了估计器的性能。本文表明,在这类最佳接收机的设计中匹配滤波器,相关接收机是最为重要的部件。其中实现载波恢复,同步提取的锁相技术或同步技术又是十分关键的。
This article from the best point of view of the best estimate of the time-frequency coded signal diversity demodulator program design. In this paper, the relation of maximum likelihood estimation under white (or non-white) additive Gaussian noise is deduced and analyzed. The optimal amplitudes of binary OOK and PSK signals of unknown phase under white (or non-white) additive Gaussian noise The estimated relationships and the best estimator scheme. This article from several aspects of the analysis proved the best of this estimation, uniqueness. The performance of the estimator is given. This article shows that in the design of the best receiver of this type matched filter, the relevant receiver is the most important part. The realization of carrier recovery, synchronous extraction of the lock-in technology or synchronization technology is very crucial.
