An ICTF-TPWC Approach To Reduce PAPR of The OFDM System
Journal Title: IOSR Journal of Electronics and Communication Engineering(IOSR-JECE) - Year 2018, Vol 13, Issue 6
Abstract
One of the important factor to be considered in a communication system is its peak to average power ratio. In this paper an effective technique named Iterative Companding Transform and Filtering –Two piecewise Companding (ICTF-TPWC) is preferred which decreases the Peak to Average Power Ratio (PAPR) as well as Bit Error Rate (BER) in an Orthogonal Frequency Division Multiplexing (OFDM) signal. Here it can be seen that without conducting de-companding at the ICTF receiver it can offer improved BER. In simulations comparisons of traditional ICF technique with proposed ICTF-TPWC technique is done in which ICTF-TPWC reduces the complexity by reducing the number of Iterations when compared to ICF to reach the required PAPR with lesser complications. ICTF-TPWC scheme offers a good BER performance when compared to the traditional techniques.
