Abstract: Nowadays, a major challenge in communication is to send maximum possible information through minimum Band Width. Orthogonal Frequency Division Multiplexing (OFDM) has opened an era for both wired and wireless communication to enhance spectral efficiency to a maximum extent. Time variance of wireless channels destroys the orthogonality among subchannels in Orthogonal Frequency Division Multiplexing (OFDM) system and causes Inter Channel Interference (ICI), which result in an error floor. In this paper, we study Partial Response Coding(PRC) for reducing the effect of the Inter Channel Interference (ICI). Based on the general expression of the ICI power for OFDM with PRC, the optimum weight for PRC that minimize the ICI power has derived. Numerical and simulation result shows that use of more tap have the ability to reduce ICI.
