Field Extension Code Based Dispersion Matrices for Coherently Detected Space-Time Shift Keying
Field Extension Code Based Dispersion Matrices for Coherently Detected Space-Time Shift Keying
Abstract—Motivated by the recent Coherent Space-Time Shift Keying (CSTSK) philosophy, we construct new dispersion matrices for rotationally invariant PSK signaling sets. Given a specific PSK signal constellation, the dispersion matrices of the existing CSTSK scheme were chosen by maximizing the mutual information over randomly generated sets of dispersion matrices. In this contribution we propose a general method for constructing a set of structured dispersion matrices for arbitrary PSK signaling sets using Field Extension (FE) codes and then study the attainable Symbol Error Rate (SER) performance of some example constructions. We demonstrate that the proposed dispersion scheme is capable of outperforming the existing dispersion arrangement at medium to high SNRs. Index Terms—Field Extensions, Cyclotomic Fields, Space-Time Shift Keying, Coding gain, Diversity.
