In this paper, Space Time Block Code (STBC), Spatial Multiplexing (SM) and hybrid model with OFDM are designed for Rayleigh fading channel. Combination of SM and STBC forms hybrid MIMO model. The performances of the above mentioned models with different modulations such as Quadrature Phase Shift Keying (QPSK) and Quadrature Amplitude Modulation (QAM) with multiple antennas are measured with respect to BER. In this paper, it is shown that Hybrid MIMO provides low BER. Thus, in wireless communication, hybrid model improves the data rate and link reliability.
