High-Throughput Non-Orthogonal Interleaved Random Space-Time Coding for Multi-Source Cooperation

Abstract— In this paper, we propose a novel distributed Interleaved Random Space-Time Code (IR-STC) designed for MultiSource Cooperation (MSC) employing various relaying techniques, namely Amplify-Forward, Decode-Forward, Soft-Decode-Forward and Differential-Decode-Forward. We characterise the achievable slot utilisation efficiency and introduce a two-phase communication regime for our IR-STC aided MSC. A matrix based formalism is used for describing our IR-STC scheme and a novel Structured Embedded (SE) random interleaver generation method is proposed. Furthermore, the Bit Error Ratio (BER) performance of our IR-STC is characterised in conjunction with various relaying techniques under different inter-source Nakagamim fading channels.
