Turbo coded MIMO-OFDM systems

Increasing demand for high-performance 4G broadband wireless is done by the use of multiple antennas at both sides transmitting and receiving. Multiple antenna technologies allow high capacities suited for Internet and multimedia services, and also increase range and reliability of communication systems. Orthogonal frequency-division multiplexing (OFDM) is a popular method for high-data-rate wireless transmission over multipath fading. OFDM may be combined with multiple antennas at both the access point and mobile terminal to increase diversity gain and to enhance system capacity on a time-varying multipath fading channel, resulting a multiple-input multiple-output OFDM system. In this article, we describe a multiple input multiple output OFDM wireless communication system, with compressed technique i.e. Turbo Code. By this, increased capacity, coverage, and reliability of communication systems are clearly evident from the results presented in this article. Thus, the simulation results of BER plot show the effectiveness of our proposed practical image transmission system.
