Comparative Study of Channel Codes for OFDM System and Judgement for Batter Peak to Average Power Ratio (PAPR)

Orthogonal Frequency Division Multiplexing (OFDM) system is used for the reducing almost every kind of interference in any communication system. For designing OFDM system need to use FFT and IDFT phenomena of signal processing, in this work mainly concern to improve peak to average power ratio for this system because this system is multicarrier system, and in the multiple carriers are nearly having same frequency but still they do not overlap to each other because these multiple carriers are orthogonal to each other. These multiple carriers have different power and energy levels so we get very unfair PAPR for this system here channel codes can be use to improve PAPR for that system, so in this work we will focus on the Comparing PAPR of OFDM system for different Channel codes.
