OFDM is a excellent technique for high speed data transmission using orthogonal channels and also provides excellent immunity against fading and ISI. But a major problem with OFDM is its high Peak to Average Power Ratio (PAPR), which decreases the efficiency of the power amplifier. Complementary Code Modulation is one of the techniques to reduce the PAPR of the OFDM signal. To make this technique more efficient, 1Time Interleaving and Time Interleaving with Bandwidth Efficiency is used to reduce the PAPR. Finally, the Complementary Coded Signal is been decoded to get the original data by Suboptimal Decoding.
