Communication is one of the important aspects of life. With the advancement in age and its growing demands, there has been rapid growth in the field of communication. Initially, the transmission of signals in analog domain was in more demand, but now-a-days, the trend is turning more towards digital signal transmission. The reason being inherent advantages of digital transmission over analog transmission. For better transmission, even single-carrier waves are being replaced by multi-carriers. Multi-carrier systems like CDMA and OFDM are now-a-days being implemented. There are a number of techniques to deal with the problem of PAPR (Peak-to-Average Power).
