New Transmission Channel Scheme for MIMO-OFDM System

In this paper, presentation on channel coding scheme for MIMOOFDM systems. Multiple-input Multiple-output (MIMO) combination with orthogonal frequency division multiplexing (MIMOOFDM) wireless technology is forming an attractive air-interface solution for  wireless metropolitan area networks (WMANs), wireless local area networks (WLANs) and mobile cellular wireless system.  It increases bit error rate (BER) performance and data rate. The new scheme is efficient for symmetric channels like radio beam transmission link between two antennas between or two base stations. The principle is based on the channel parameter of a pilot data send by the receiver to the transmitter. It adapts the signal to the channel variation which occupies by the transmitter code signal using estimation of channel parameters. In case of symmetric channel it compared to the conventional MIMOOFDM scheme has better complexity and bandwidth efficiency.
