Abstract :
A proposition is described in this paper regarding the use of algebraic space-time code (ASTC) and minimum mean square error equalizer (MMSE) for the amelioration of the bit error rate (BER) in the orthogonal frequency division multiplexing (OFDM) and multiple-input multiple-output (MIMO) systems so as to deduce the desired outcomes. The MATLAB SIMULINK R2012.a is incorporated here for the modeling and simulation results and the same are plotted for BER performance of OFDM in MIMO system Vs Eb/No. Also the different fading channels i.e. additive white Gaussian noise, Rayleigh and Rician channel have been inculcated and the BER performance ameliorates overwhelmingly thereby depicting the desired enhancement incorporating MMSE equalizers and ASTC encoder in several fading channels, i.e. approximately 10% - 20% in OFDM and in MIMO-OFDM it improve up to 15% approximately. The relative analysis of the conclusion and observations described in the recommended system show an improvement than the MMSE equalizer tremendously.
