In this paper, the authors design a communication system with transmitted symbols under flat fading channel and estimate the channel by Least Square (LS) approach and Linear Minimum Mean Square Error (LMMSE) approach for channel coefficients. They analyze the link-to-system interface for MIMO-OFDM system level simulations and propose an efficient method for calculation of the effective SINR. The accuracy of the proposed effective SINR is evaluated by simulated BLER performance comparison. In this paper, efficient SINR computation using LMMSE approach, reduction in the BLER is obtained with reduced computational complexity.
