The Research of MIMO-OFDM System in the Fourth Generation Mobile Communication
This paper refers to MIMO-OFDM (multiple input multiple output orthogonal frequency-division multiplexing) system studies in the fourth generation mobile communication. We have designed two schemes, one is two transmit antennas and one receive antenna, and the other is two transmit and two receive antennas. In this system we use MPSK modulation, Alamouti space-time coding, RS coding in channel transmission. We analyze the systems error performance by simulation, and prove the design is feasible. The system not only provides highly frequency spectral efficiency but also has better error performance. The research is a promising approach used in the future communication and has tremendous potential.
