A channel estimation solution for use in an OFDM MIMO-enabled communication system that includes: receiving a plurality of received signal sets that each respectively include a consecutive set of superimposed time-domain signal blocks; processing the set of received signals by at least converting the consecutive set of superimposed time-domain signal blocks from the time-domain to the frequency-domain by transforming the consecutive set of superimposed time-domain signal blocks to a set of incomplete observed data; and estimating a plurality of a set of channel estimates. The estimation of the plurality of a set of channel estimates includes performing a plurality of iterative processes, where each iterative process includes using a current set of incomplete observed data, calculating a set of decomposed signals, and calculating a set of current channel estimates until the iterative process converges. Detecting the transmitted frequency-domain signal blocks by at least using a set of last channel estimates, tracking the channels, or both, may be further included. |
