Abstract

Abstract:

The decoding complexity of conventional differential space-time-frequency codes based on maximum-likelihood (ML) differential detection increases quickly with the number of constellation components and transmitted information symbols. By grouping the constellation, a fast decoding algorithm is proposed. The proposed algorithm provides performance close to that of the ML differential detection, that is, both can achieve maximum space-multipath diversity, but the proposed algorithm offers a lower decoding complexity. Analytical evaluation and corroborating simulations reveal its performance merits.

Key words: multiple input multiple output, space-time block code, differential space-time-frequency coding, differential decoding, frequency-selective channel, space-multipath diversity
