| Abstract |
In this paper, we propose a novel distributed Interleaved Random Space-Time Code (IR-STC) designed for Multi-Source 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 Multilevel Structured (MLS) random interleaver generation method is proposed. We characterize the achievable performance of our proposed IR-STC design compared to that of the traditional $G_4$ Orthogonal Space-Time Block Codes (OSTBC) invoked for MSC and the performance of our IR-STC is furthermore characterised in conjunction with various relaying techniques under different inter-source Nakagami-m fading channels. |
