“…It uses the PTS scheme for PAPR reduction technique well as increasing the number of weighting factor and clusters this new PTS system with the simultaneous calculations is that each bunch is partitioned into 2 sections and these two sections utilize the diverse weighting factors having some connection between them. The main feature of this technique is by using same size of side information PAPR performance can be improved [8].…”

An extremely attractive procedure for fast airing over a dispersive correspondence channel is Multicarrier transmission. PAPR has a badly-behaved imperative concern to be spoken in evolving multicarrier broadcast systems. In this article PAPR reduction procedure has been designated for multicarrier transmission. In this developed technique a promising for the reduction of PAPR without loss of data transmit signal and BER of MIMO OFDM presented, but computational complexity has increased as increasing number of transmitter antennas Mt. A technique is used for finding of constant modulus (CMA) signal in such a way that beam forming weights have multiply with their orthonormal data matrix. That prime solution is an evolutionary adaptive constant modulus algorithm (EA-CMA) for optimal search of least PAPR signal. The results are simulated for QPSK, 16QAM and 64QAM modulation schemes with MATLAB 2013 version. This technique is compatible with PTS (Partial transmit sequence) scheme

“…Signal scrambling techniques do not twist the structure of the OFDM signal and no spectral regrowth occur. These schemes incorporate coding schemes [1][2][3] which cause no distortion and make no out of band radiation, but experience from bandwidth efficiency as the code rate is lessened and also suffer from complexity to discover best codes for an expansive number of subcarriers, both PTS [4][5][6][7][8][9] and SLM [10][11][12][13][14][15] schemes accomplish significant PAPR reduction at the expense of high computational complexity and data rate loss (side information). Signal distortion methods introduce spectral regrowth or distort the spectrum of the signal and transmit a PAPR signal with no extra data.…”

Orthogonal frequency division multiplexing (OFDM) is a prominent, new multicarrier modulation technology used with most 4G wireless communication systems. It was configured with MIMO to transmit very high rates of digital information with enhanced performance and speed. However, OFDM faced high peak to average power ratio (PAPR) issue at the transmitter. In this paper, a new companding method called advanced exponential companding (AEC) is proposed to provide better PAPA and BER performance than standard exponential companding (EC) and Mu-law companding while keeping constant average power before and after companding process. In addition, a new efficient hybrid scheme that is containing Zaddoff Chu Matrix Transform (ZCT) precoding and the proposed AEC companding is developed. The new scheme lessens the signal distortion caused by AEC companding and gives a great improvement in both PAPR & BER performance in comparison with AEC in both LTE SISO-OFDM and LTE MIMO-OFDM systems. It produces high PAPR performance with slight SNR loss at 10^-3 BER against ZCT precoding with LTE MIMO-OFDM system. It offers the best results in terms of PAPR & BER against those related existing hybrid methods, namely; discrete hartley transform (DHT) precoding + Mu-law companding, Zadoff -chu matrix transform (ZCT) + Mu-law companding, Walsh Hadamard Transform (WHT) precoding + Mu-law companding, Walsh Hadamard Transform (WHT) precoding + exponential companding (EC), and discrete cosine transform (DCT) precoding + Mu-law companding for LTE SISO-OFDM system.
