In modern scenario demand for high data transmission rates with the evolution of the very large scale integration (VLSI) technology is very high. The multiple input multiple output-orthogonal frequency division multiplexing (MIMO-OFDM) systems are used to fulfill these requirements because of their unique properties such as high spectral efficiency, high data rate and resistance towards multipath propagation. MIMO-OFDM systems are finding their applications in the modern wireless communication systems like IEEE 802.11n, 4G and LTE. They also offer reliable communication with the increased coverage area. Orthogonal Frequency Division Multiplexing is used to improve spectral efficiency and Multiple Input Multiple Output (MIMO) is used to improve spatial diversity in today wireless communications systems. This paper provides Bit Error Rate analysis For MIMO-OFDM Using Spatial and Temporal Correlations & analysis of performance of OFDM with MIMO-OFDM. MIMO OFDM is superior approach that exploits spatial and temporal correlation of Multiple Input Multiple Output (MIMO). Therefore this technology covers benefits of MIMO with advantages of OFDM. Finally, paper provides analysis of performance of MIMO-OFDM over conventional OFDM and found MIMO-OFDM is superior. Our Simulation result shows improvement in SNR according to BER after comparing both the techniques.
