Joint Channel Impulse Response and Noise-Variance Estimation for OFDM{\slash}SDMA Systems Based on Expectation Maximization

, 2010
A joint channel impulse response (CIR) and noise-variance estimation scheme is proposed for multi-user Multiple-Input-Multiple-Output (MIMO) Orthogonal Frequency-Division Multiplexing\,/\,Space Division Multiple Access (OFDM/SDMA) systems, which is based

Iterative joint channel and data estimation for rank-deficient MIMO-OFDM

, 2007
In this paper we propose a turbo-detected multi-antenna-multi-carrier receiver scheme. Following the philosophy of the turbo processing, our turbo MIMO-OFDM receiver comprises a succession of detection modules, namely the channel estimator, the space ...
