COMPARATIVE STUDY OF PAPR REDUCTION ON SPECTRUM AND ENERGY EFFICIENCIES USING CLIPPING AND FILTERING TECHNIQUE AND PARTIAL TRANSMIT SEQUENCE TECHNIQUE IN OFDM SYSTEM
Journal Title: International Journal of Innovative Research in Advanced Engineering - Year 2016, Vol 0, Issue 0
Abstract
In this paper an economical study is done among simple clipping and filtering procedures and partial transmit sequence procedure, and proved that spectrum and energy efficiency is much better in comparative with the partial transmit sequence technique. To prove the results the structure of orthogonal frequency division multiplexing is created and then two various parameters of dimension are done. The parameters are comparison of Peak to average power ratio versus complementary cumulative distribution function and spectrum efficiency versus energy efficiency. The parameters taken for number of subcarriers are differing with number of fft transporters, for the comfort of number of Fourier change. The numbers of subcarriers are normally taken to be 64, 128,256, and 512. The number of bits for transmission is differing between 2000 to 4000. The work is to be completed by using three different modulation techniques, i.e. binary phase shift keying, quadric phase shift keying, quadrature amplitude modulation. The best execution is done and acquired utilizing regulation of sort quadric stage shift keying, when cutting and separating has indicated better results.
