Channel estimation, which is a key task in massive multiple-input multiple-output orthogonal-frequency division-multiplexing systems (MIMO-OFDM), is severely affected by the problem of pilot contamination during the uplink transmission. Thus, the aim

Nonlinear distortions are important issues in many communications systems. Therefore, this paper deals with the blind and semi-blind identification of nonlinear SIMO/MIMO channels. Quadratic and cubic nonlinearities are considered for the system mode

The aim of this paper is to propose a semi-blind solution, for joint sparse channel estimation and data detection, based on the successive convex approximation approach. The optimization is performed on an approximate convex problem, rather than the
