Abstract
This work introduces a new semi-blind multi-modulus approach for joint source separation and carrier frequency offset (CFO) estimation in Multiple-Input Multiple-Output Orthogonal Frequency Division Multiplexing communications. A hybrid semi-blind cost function based on the Least Squares (LS) and Multi-Modulus (MM) is designed for source recovery and CFO estimation. An alternating gradient descent optimization method is utilized to iteratively minimize the cost function along the search direction. Furthermore, an efficient initialization procedure is introduced to reduce the algorithm's complexity and ensure its convergence. The simulation results show that our method performs very well in terms of CFO estimation and data recovery.
