Abstract :

ABSTRACT Channel estimation scheme based on minimum mean square estimation (MMSE) and sparse message passing (SMP) has been proposed .This can yield better performance since it can capture the inherent sparseness of the millimeter wave (mm wave) channel. MMSE-SMP algorithm reduces the pathloss,fading, shadowing effects, co-channel interference, channeluncertainitiy. This effects can be reduced by increasing the number of transmit antennas and receive antennas. Also, MMSE-SMP does not require the prior knowledge of the channel distribution and provide better performance. Even with less number of transmit and receive antennas itself can provide better performance. Index Terms:Sparse Message passing (SMP), Minimum Mean Square Estimation (MMSE), Millimeter wave, Iterative Channel Estimation.
