摘要：OFDM is a multiplexing technique developed to cater the requirementof high data rate with robustness againstthe adverse effects that may occur over the path of transmission. The OFDM based broadband communication system suffers disturbances due to fading over multiple paths that it take to the receiver. In addition to fading, it is alsoaffected by different noises. AWGN andIN are considered to analyze the performance of the system. In order to jointly fight the effect of fading and noise, an MIMO-OFDM system is proposed to achieve space diversity along with the methods of Time domain interleaving(TDI) and symbol blanking that provides time diversity and frequency diversity,with an aim to reduce the Bit error rate
