Abstract

This work proposes an effective source separation technique based on a semi-blind multi-modulus approach for an embedded pilot scenario in a Multiple-Input Multiple-Output Orthogonal Frequency Division Multiplexing (MIMO-OFDM) communication system. A jointly hybrid cost function is developed based on the Multi-Modulus (MM) and Least Squares (LS) for a semi-blind channel estimation. A straightforward yet effective semi-blind block gradient descent optimization approach is used. In addition, a technique for optimizing the step size is introduced to improve the convergence rate of the proposed algorithm. The proposed semi-blind technique for a superimposed pilot scheme is compared to the Time-division Multiplexed pilots (i.e., block pilot arrangement) in terms of the symbol error rate and the throughput. The extensive simulation results demonstrate that the inherent ambiguity in the blind estimation is preserved, and the result shows excellent performance and bandwidth trade-offs.
