摘要:In this paper, the principles of a MIMO system are analyzed, in addition to how it can be used with OFDM modulation to obtain both frequency and space diversity in a terrestrial multipath Rayleigh channel. Toward this aim, an Alamouti encoder and decoder are employed, in conjunction with QPSK and 16QAM modulation schemes. From the simulation results, it is observed that MIMO, with two transmit and two receive antennas using OFDM and 16QAM, performs well in terms of received BER.
