Abstract

This paper develops schemes for orthogonal matching pursuit (OMP), bayesian Cramer Rao Bound & ORACLE-LS channel estimation technique in milli-meter wave (mm-Wave) multiple-input-multipleoutput (MIMO) systems that exploit the spatial sparsity inherent in channels. In simulation results shows comparison between ORACLE LS & orthogonal matching pursuit (OMP) on the basis of NMSE v/s SNR comparison between orthogonal matching pursuit OMP, MSBL, and TSBL-based & various channel estimation techniques for the mm-Wave MIMO whose setup parameters are as NT (No of transmitter) = 8, NR (No of receivers) = 8, NBeam = 8, R = 8, NRF = 4, Nc (No of carriers) = 5 and G = 10. Simulation result shows the improved in performance of the proposed ORACLE LSbased channel estimation techniques gives better performance in comparison to the popular orthogonal matching pursuit (OMP) based scheme.

Keywords: OMP, MSBL, TSBL-based, ORACLE LS-based, MIMO.
