RS-Coded Cooperation Scheme Based on 2 × 2 Labeling Diversity

Abstract

This paper investigates the novel labeling diversity (LD) technique with two transmit antennas and receive antennas applied in the Reed-Solomon coded cooperative (RSCC) system to propose a novel RSCC-LD scheme over the Rayleigh quasi-static fading and frequency-flat fast-fading channels. Two separate RS codes over the same Galois field are deployed at the source and relay terminals, respectively with the relay RS code providing more extra redundancy. To optimize the use of the information contained in two RS codes, a novel joint decoding approach is developed at the destination terminal. The results of numerical simulation demonstrate that the proposed RSCC-LD has an obviously better performance than the non-cooperative RS coding scheme and RSCC scheme without LD. Furthermore, the performance of the RSCC-LD reveals the superiority of some other existing schemes.
