Decoding algorithms for 3-D space-time-frequency codes

摘要

In this paper, we propose a joint complex diversity coding (CDC) and channel coding based space-time-frequency codes (STFCs) to increase diversity gains over space, time and frequency. Both non-iterative and iterative decoding of joint channel coding and 3-dimensional CDC transmission are investigated. The simulation results show that the minimum mean square error (MMSE) based iterative soft decoding achieves the performance of the soft sphere decoding (SD) with reduced complexity.
