Modern communication systems are adopting new Morden technologies like OFDM (Ortogonal Frequency Division Multiplexing) and LDPC (Low Density Parity Check) for achieving high performance, low Bit Error Rate (BER) and high capacity. The OFDM communication is inspired effectively from the frequencies of channel over the network. In this type of network some kind of distortion occurs over the channel called Inter Carrier Interference (ICI). The OFDM technique can be implemented using Low Density Parity Check (LDPC) Codes because of their ability to reaching near Shannon limit performance.
