Analysis of Golden code in multi-hop relay network

Abstract

A new concept of research is cooperative communication which is influencing technique to reduce fading in wireless relaying layout. Concerning with the fading issue, this paper focuses to giving a better non-orthogonal space-time block code (NOSTBC) scheme and assimilate it in cooperative relaying nodes for upgrading system performance. The Golden code proven to present a ranking performance in a Multiple-Input Multiple-Output (MIMO) scenario than any other code and been incorporated in IEEE 802.16 standards as a full rate and full diversity space-time code. At the receiver, maximum likelihood (ML) detection of different symbol is attained by decoupling of signal transmit from various antenna instead of joint detection. This paper of multi-hop wireless relay network consisting of source, relay and destination each equipped with two antennas have been taken into account using decode-and-forward cooperative protocol strategy in relay nodes. The simulation results support the effectiveness of the proposed scheme by offering better symbol error rate performance and increased spectral efficiency than other codes.
