This paper develops schemes for OMP, Bayesian Cramer–Rao bounds and ORACLE LS channel estimation in milli-meter wave (mm-Wave) multiple input & multiple output (MIMO) systems that work on spatial complex sparsity inherent in channels. In simulation results shows comparison between ORACLE LS & orthogonal matching pursuit (OMP) on the basis of NMSE v/s SNR. The mm-Wave MIMO whose setup parameters are taken as NT (No of transmitter) =32, NR (No of receivers) = 32, NBeam=24, RF = 8, NRF = 8, Nc l = 5 and G = 32. Simulation results shows the improvement in the performance of the proposed ORACLE-LS based channel estimation techniques gives better estimation performance in the compare to the popular OMP based technique.
