Universal Filter Multi-Carrier (UFMC) plays a significant role in an asynchronous transmission because of its high spectral efficiency. However, the effectiveness and efficacy of the UFMC systems is hindered by the high peak to average ratio (PAPR), which in turn decreases the potency of power amplifiers. Over the years, a number of approaches have been developed for reducing the PAPR in UFMC systems; however these systems used conventional PAPR reduction techniques that were highly complex and ineffective. Therefore, an improved and reliable UFMC model is proposed in this paper that is based on Partial Training Sequence (PTS) and Tree Seed Algorithm (TSA). The main objective of the proposed model is to reduce the PAPR value and complexity of the UFMC systems. To achieve the desired objective, a signal is generated at the transmitted end and upon which modulation and filtration techniques are applied by using 16-QAM modulator and ChebyShev filter. The PTS then generates a wide range of phase combinations with reduced PAPR value and TSA selects the best signal with least PAPR. The performance of the proposed hybrid UFMC model is analyzed and compared with traditional UFMC and OFDM models in MATLAB 2015 software. The simulation outcomes were determined in terms of PAPR, BER and Spectral efficiency. The results attained showcased that proposed model is providing effective results with least PAPR values.
