A Proposed Method for Improving The Performance of UFMC System in terms of PAPR and BER
Abstract
In this research, the impact of two major issues affecting the Universal Filtered Multicarrier (UFMC) system was mitigated: the high peak-to-average power ratio (PAPR) and intercarrier interference (ICI) which leads to the degradation of the bit error rate (BER) and consequently, the overall system performance. A method was proposed to simultaneously reduce both PAPR and BER by applying the selective mapping (SLM) technique in combination with the data conjugate method within the UFMC system. Simulations were conducted using MATLAB, and the results demonstrate that the proposed method offers superior performance compared to the standard UFMC system. For 16QAM modulation and frequency offset ε=0.05, the BER reaches 10-5 at Eb/No≈15.5dB. Additionally, the PAPR was reduced by approximately 2.25dB compared to standard UFMC system.
