Linear detection analysis in MIMO-OFDM with spatial correlation

This work analyses the performance of the orthogonal frequency division multiplexing (OFDM) technique, which is widely employed in wireless communication. The modified Jakes model for expeditious fading coefficients generation is adopted aiming to analyse and evaluate realistic communication channel scenarios. Multiple-input multiple-output (MIMO) OFDM systems were analysed for the purpose of achieve high performance combined with high capacity systems. Numerical results for bit-error-rate (BER) performance under different system and channel scenarios were obtained via Monte-Carlo simulation. Moreover, channel selectivity are discussed in SISO-OFDM while the impact on the system performance of the number of antennas, adoption of linear detection schemes and the spatial correlation are analysed in MIMO-OFDM context.
