摘要

时间和频率同步的可分离性(SP)条件迫使我们确定Gabor分/扩频系统(GD/S3)中的相位校正项。相位校正技术使我们设计了一种具有相位调谐层的GD/S3接收机，用于多级相移键控(MPSK)。当M = 16时，每层时域(TD)和频域(FD)相关器输出的结果信号点仅由三条线组成，称为相位角与层相关的主瓣和相位角为±2π/16的副瓣。受码分多址(CDMA)思想的启发，采用码分多址(CDMT)技术消除了提示误码的两个副瓣。验证了16PSK的仿真结果。

Phase-tuned layers with multiple 2D SS codes realize 16PSK communication

The Separable Property (SP) condition for time and frequency synchronization compels us to determine phase correction terms in the Gabor Division/Spread Spectrum System (GD/S3). The phase correction technique has led us to design a GD/S3 receiver equipped with phase-tuned layers for Mary phase shift keying (MPSK). The resulting signal points of the time domain (TD) and frequency domain (FD) correlator outputs of each layer for M = 16 consist of only three lines, called a main-lobe with a layer-dependent phase angle and sidelobes with phase angle ±2π/16. The two sidelobes suggesting bit errors are removed by using code division multiple target (CDMT), inspired by code division multiple-access (CDMA) philosophy. The simulation result for 16PSK is confirmed.
