Abstract

In this paper, we propose a simple MIMO-OFDM with time and frequency domain spreading for mobile environment. The transmission scheme that we propose in this paper is a simple method with low complexity for improving the performance of conventional SFBC-OFDM. Using Hadamard transformation in time and frequency domain, we can obtain space, time and frequency diversity gain. Also we propose the spreading hybrid MIMO-OFDM system combined spreading SFBC-OFDM with SM scheme.
