摘要：

Multiple antennas are used in wireless systems to achieve good quality of service and high data rate communication. Multiple-input multiple-output (MIMO) communication systems have a great potential to play an important role in the design of the 4G broadband wireless communication systems. In this paper, performance analysis of combined beamforming with space-time-frequency (STF) coded MIMO-OFDM systems is carried out using computer simulation. The proposed framework incorporates the beamforming with STF coding at the transmitter while minimum mean squared error (MMSE) and maximum likelihood (ML) detection at the receiver are considered. Simulation results show that the proposed scheme achieve significant performance gain in terms of bit error rate (BER).
