本文介绍了一种用于56吉波特相干光双偏振正交相移键控GEO馈线链路的定制数字信号处理接收机和伴随帧格式的设计。所选择的算法结合了来自相干光纤和RF卫星通信的联合收割机标准实践。稳健的盲算法用于第一阶段，随后的数据辅助算法用于随后的精细载波和相位恢复。提出了一种基于修正恒模算法的简化盲均衡器结构，用于快速、鲁棒的偏振解复用。我们的模拟表明，在低至-6 dB的电SNR建立链路的可能性，在现实的系统损伤值的存在下，使用小于5%的信令开销。
This paper addresses the design of a custom digital signal processing receiver and companion frame format for a 56 GBaud coherent optical Dual-Polarization Quadrature Phase-Shift Keying GEO feeder link. The selected algorithms combine standard practice from both coherent optical fiber and RF satellite communications. Robust blind algorithms are used in the first stages, followed by data-aided algorithms for subsequent fine carrier and phase recovery. A simplified blind equalizer architecture is proposed for fast and robust polarization demultiplexing, based on a modified constant-modulus algorithm. Our simulations demonstrate the possibility to establish links at an electrical SNR as low as -6 dB, in the presence of realistic values of system impairments, using less than 5% signaling overhead.
