A Low Complexity Architecture for Papr Using Hadamard SLM in SFBC OFDM System
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 1
Abstract
In this paper, we propose a hadamard SLM for the reduction of high peak to average power ration (PAPR) in OFDM systems. In this technique, follows two staps, firstly,The input information is multiplied by a set of phase rotation vectors respectively. Secondly, apply the hadamard transform of each resulting sequence based on SFBC. After to compute the inverse fast fourier transform to get the time domain signal. The proposed method has less computation complexity and better PAPR performance. The experimental results shows that the PAPR reduction performance of hadamard SLMtransform technique and compare to SLM and SLM-2 techniques.
