提出了一种适用于星星16 QAM的多符号差分检测方案。首先，我们分析了传统的差分检测星星16 QAM。结果表明，与理想相干检测相比，差分幅度检测的能量损失大于相位检测的能量损失。为了提高星星16 QAM的整体性能，本文提出了一种大C/N的MLSE算法和一种次优算法。它们都允许多符号差分幅度和相位检测。并通过计算机仿真对其性能进行了评价。
This paper addresses a multiple-symbol differential detection scheme for star 16QAM. At the outset, we analytically scrutinized conventional differential detection of star 16QAM. As a result, it emerged that the energy penalty of differential amplitude detection as compared with ideal coherent detection is larger than that of phase detection. Then to improve the overall performance of star 16QAM, we propose an MLSE algorithm for a largeC/Nas well as a suboptimum algorithm. Both of them allow multiple-symbol differential amplitude and phase detection. Their performances are also evaluated through computer simulation.
