The OFDM (Orthogonal Frequency Division Multiplexing) technology provides high bit rate, spectral efficiency and helps to mitigate ISI (InterSymbol Interference) in wireless environment. In case of fading channel the BER (Bit Error Rat) increases, hence channel coding technique with interleaving is used to improve the performance. In this paper, convolutional coding along with matrix and random interleaving is used to enhance the system performance. The modeling and simulation of OFDM system is carried out and the BER performance of matrix and random interleaving is compared.
