摘要
本文基于最大后验概率估值原理,提出一种新的相敏检测方法,文中给出了判决量的计算公式和所提出方法的数字信号处理器实现结构。计算机模拟结果表明,所提出的方法较Saniie所提出的正交采样数字相敏方法有更好的检测性能。
Based on the maximum posterior probability(MAP)estimation,a new method for phase sensitive detection is proposed.Decision equations are derived and block diagrams of DSP implementation of the MAP method are given.Computer simulation results show that better detection performances can be obtained by the MAP method than by the in-phase and quadrature sampling one developed by Sanile.
