Channel Estimation for MIMO based-Polar Codes

The popular scheme for estimating the wireless channel is through the transmission of pilot or training
symbols. pilot symbols are a predetermined fixed set of symbols which are transmitted over the wireless channel. This set
of symbols is known to the wireless receiver as it is programmed beforehand. The receiver observes the output
corresponding to the transmitted pilot symbols and with knowledge of the transmitted pilot symbols, proceeds to estimate
the unknown fading channel coefficient.
