Abstract

A semi-blind time-domain equalization technique is proposed for general MIMO OFDM systems. We proposed new algorithm of received signal with pilot, that design need to our project, so we discuss to interference cancellation algorithm for 2x2 MIMO in LTE. For pilot based channel estimation of OFDM system, following two are required. Firstly, suitable pilot pattern needs to be considered. Secondly, pilot-based channel estimation algorithm with low complexity should be identified. Finally we implemented our mathematic extraction of proposed new source algorithm on MATLAB.
