An Enhanced Dual-polarized Transmission System with 4D-TCM 8PSK Modulation and XPIC
Byeongjae Kim, Donghyun Kim · 2020
In this paper, we design a communication system with 4D-TCM 8PSK, which is one of the modulation schemes for space communications recommended by CCSDS and ECSS. In particular, we consider dual polarization transmission that can induce an interfering issue between individual polarization signal. To alleviate it, we propose a type of Cross-Polarization Interference Cancellation (XPIC) reception strategy that does not require additional pilot symbols in estimating Cross-Polarization Discrimination (XPD). We evaluate the goodness of the proposed strategy with simulator by comparing the measured BER with those of the other baseline schemes.
