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).
