Performance Of Lte Communication System In Correlated Rayleigh Channel With Different Antenna Configurations

Long Term Evolution (LTE) standard supports MU-MIMO as a new technology to take advantage of the inherent properties of MIMO technology in improving the spectral efficiency and to support multiple users simultaneously. This paper studies the performance of the SC-OFDMA-based LTE system in the uplink correlated Rayleigh fading channel in terms of bit error rate (BER). To the best of author knowledge, the performance of such an LTE system incorporating Successive Interference Cancellation Minimum Mean Square Error (SIC-MMSE) receiver in correlated Rayleigh channel was not previously investigated, more particularly with different antenna configurations. The choice of such a receiver is motivated by its relative complexity and computation reduction.
