Abstract

Orthogonal frequency division multiplexing (OFDM) is a famous technique for high information rate remote transmission. OFDM might be joined with antenna arrays at the transmitter and recipient to expand the differences pick up and/or to upgrade the framework limit on time-variant and frequency-specific channels, resulting in a multiple-input multiple-output (MIMO) arrangement. In this paper we are introducing MIMO-OFDM. We measured the performance of different modulation techniques with respect to BER and SNR. We compare the results and conclude that in the case of even power, bit error rate is lower as compare to odd power.

Keywords: Multiple-input multiple-output (MIMO), orthogonal frequency division multiplexing (OFDM), software radio, space–time coding, syn-chronization.
