Coded Orthogonal Frequency Division Multiplexing (COFDM) is one of the dominant techniques of present day wireless (mobile) communication. The main advantage of OFDM is that it makes the receiver highly robust against Multipath fading environments. Due to orthogonal properties of the sub-carriers used, OFDM also provides efficient spectrum utilization by use of single frequency networks (SFNs) and use of simple equalizers. OFDM has become the standard for physical layer implementation of various digital audio and video wireless communications such as DAB/DVB, wireless local access networks (WLANs) and wireless metropolitan area networks (WMANs). In this paper, we present a performance analysis of a (COFDM) using convolutional coding, interleaving with different digital modulation techniques in diverse transmission channels. The results show that COFDM is well suited for high speed data transmission in mobile environment and interleaving is essential for reducing bit error rate (BER) for high speed transmission.
