THROUGHPUT IMPROVEMENT UTILIZING NOVEL PROPOSED MODEL COMBINING BCH (N, K) CODE WITH STBC CODE OVER MIMO SYSTEM WITH RAYLEIGH FADING CHANNEL

Abstract

Several coding schemes have been implemented to improve capacity (throughput), minimize bit error rate, and the effect of fading. MIMO technique is stilling a powerful technique besides channel coding. The structure of the proposed system model relies on channel coding represented by BCH (n, k) code combined with MIMO-STBC code. In this research paper, focus on utilizing accessible wireless communication resources to improve the efficiency of the MIMO system in terms of capacity (throughput) and coding gain utilizing the proposed model combining BCH (n ,k) code with STBC code over MIMO system with Rayleigh fading channel. Therefore, the outcomes achieved by the proposed model gave a better improvement in coding gain and capacity (throughput). Relative to BCH (31, 26), the improvement in coding gain about 6.94 dB and achieved even better improvement if increase length of BCH code. Thus, for BCH (31, 11), the improvement in coding gain about 16.9 dB at BER (10-3). Additionally, the improvement in system performance reaches (65%-100%). This work is executed utilizing MATLAB simulation. The findings are analyzed and compared.
