The MIMO technology with modulation techniques provides high bit rate, spectral efficiency and helps to mitigate ISI in wireless environment. In case of fading channel the BER increases, hence channel coding technique with interleaving is used to improve the performance in wireless communication. In this paper convolution coding along with matrix interleaving is used to enhance the system performance for different modulation techniques. The modeling and simulation of MIMO diversity system is carried out and the BER performance of interleaving, encoder and simple MIMO diversity is compared.
