摘要

本文介绍了用于偏振移键控调制(POLSK)的多包络三维星座。星座的信号点位于两个同心球体的表面。在接收机中，采用了两种解调方案。一种是斯托克斯参数的常规相干检测(CD)。另一种是基于最大似然(ML)算法。仿真结果表明，在加性高斯白噪声(AWGN)环境下，采用ML接收机的16元立方体中立方体(CIC)星座具有最佳的误差性能。

Multi-envelope 3-dimensional constellations for polarization shift keying modulation

In this paper, multi-envelope 3-dimensional (3-D) constellations for polarization shift keying modulation (POLSK) are introduced. Signal points of the constellations are on the surfaces of two concentric spheres. In the receiver, two kinds of demodulation schemes are exploited. One is the conventional coherent detection (CD) of the Stokes parameters. The other is based on the maximum-likelihood (ML) algorithm. As a result of simulation, the 16-ary cube-in-cube (CIC) constellation with the ML receiver shows the best error performance in the additive white Gaussian noise (AWGN) environment.
