Selective Mapping scheme based on Modified Forest Optimization Algorithm for PAPR reduction in FBMC system

Abstract

Filter Bank Multicarrier(FBMC)is considered as one of the most standardized waveform for fifth generation (5G) mobile communication system application FBMC endures lot of nonlinear effects which occurs because of high Peak Average Power Ratio (PAPR). High value of PAPR due to the large dynamic range of multicarrier signal is one of the most significant issues in FBMC multicarrier based modulation technique. This paper presents one investigated PAPR reduction technique named as Selected Mapping (SLM) to minimize high PAPR by utilizing the complex signal divide into real and imaginary parts and then select minimum PAPR signal based on Modified Forest Optimization Algorithm (MFOA)to achieve good PAPR which can maintain the FBMC based system performance with a required Bit Error Rate (BER). The associated method was produced with the aim of optimize the phase factors so that the phase rotation operation is accomplished to minimize PAPR by fixing the MFOA into the conventional SLM. The simulation results demonstrate that the proposed technique gives better performance in terms of BER and PAPR compared to other SLM based optimization techniques.

Evaluation of OFDM system in terms of PAPR and BER using PAPR Reduction Techniques : Windowing and Clipping

“…Therefore, it is essential to create a framework that successfully clips the appropriate regions to lessen the PAPR problem. The PAPR problem is what causes the OFDM system to degrade [6]. In addition to the non-linear challenge of developing the PAPR problem, another circumstance arises when the receiver employs FFT to transfer the signal from the time domain to the frequency domain.…”

PAPR and BER Analysis in FBMC/OQAM System with Pulse Shaping Filters and Various PAPR Minimization Methods

“…One of the most major problems with the FBMC is the large amount of PAPR due to the high dynamic range of the multicarrier signal. The paper [16] explained a Modified Forest Optimization Algorithm(MFOA) algorithm based on Selected Mapping(SLM), to minimize PAPR and required Bit Error Rate (BER). Studies of the PHYDYAS filter in [17], the Hermite function filter in [18], and the IOTA filter in [19] address the FBMC specific shaping filters.…”
