Advancements in PAPR Reduction for Wireless Networks Using UFMC Model and QAM Modulation

Problem Definition

The use of UFMC as a multi-carrier system faces certain limitations and challenges that need to be addressed. One key issue is the lack of widespread adoption of UFMC compared to other multi-carrier systems. This is likely due to the unique approach of UFMC, which involves grouping assigned subcarriers into different sub-bands filtered independently. The lack of in-depth research and analysis on UFMC further compounds the problem, making it difficult to evaluate its performance and compare it to other established multi-carrier systems. Additionally, the high Peak-to-Average Power Ratio (PAPR) of the signals transmitted using multi-carrier modulation is a significant drawback.

High PAPR not only degrades the overall performance of the MCM system but also hampers the efficiency of low-PAPR power amplifiers, leading to reduced effectiveness and increased energy consumption. To address these issues, a novel model using UFMC system needs to be developed to reduce the PAPR and improve packet transmission with low latency. By overcoming these limitations and challenges, UFMC can potentially emerge as a more effective and efficient multi-carrier system in the telecommunications industry.

Objective

The objective is to address the limitations and challenges faced by UFMC as a multi-carrier system, particularly focusing on the lack of in-depth research, high PAPR, and inefficiencies in packet transmission. The proposed work aims to develop a novel UFMC model that reduces PAPR by incorporating techniques like a Butterworth filter and Partial Transmit Sequence method. By comparing UFMC with OFDM using QAM modulation techniques in different channels, the study seeks to enhance packet transmission efficiency and establish UFMC as a more effective multi-carrier system in the telecommunications industry. Through comprehensive performance analysis, the study aims to optimize UFMC systems for improved overall performance and effectiveness.

Proposed Work

The proposed work aims to address the research gap in the evaluation and performance validation of UFMC as a multi-carrier system, particularly focusing on its comparison with other widely used systems like OFDM. The key objective is to reduce the high PAPR associated with UFMC by incorporating techniques such as a Butterworth filter and Partial Transmit Sequence method. By analyzing the performance of UFMC and OFDM using QAM modulation techniques in the presence of AWGN and Rayleigh channels, the study will provide insights into the effectiveness of reducing PAPR for enhancing packet transmission with low latency. The selection of QAM modulation with UFMC and OFDM is supported by the advantages it offers, such as integration with MIMO systems and enabling communication with low delay. The proposed technique's main focus on reducing PAPR in UFMC will be achieved through the utilization of Partial Transmit Sequence and Butterworth filter due to their benefits, including high linear phase response in the pass-band, effective group delay performance, and reduction in the level of overshoot.

By utilizing these techniques and conducting a comprehensive performance analysis, the study aims to contribute to the optimization of UFMC systems for enhanced packet transmission efficiency.

Algorithms Used

OFDM is used for packet transmission in a wireless medium along with UFMC in this project. The performance of both models is analyzed using QAM modulation techniques and the Bit Error Rate (BER) is measured in AWGN and Rayleigh channels for the UFMC system. The project focuses on four different modulation schemes (2QAM, 4QAM, 16QAM, and 64QAM) to understand the functioning of UFMC and OFDM in detail. The advantage of using QAM with UFMC and OFDM is its ability to integrate with MIMO and enables communication with low delay. Partial Transmit Sequence (PTS) and Butterworth filter are utilized in the project to reduce the Peak-to-Average Power Ratio (PAPR) in the UFMC model.

The Butterworth filter is chosen for its high linear phase response in the pass-band, effective group delay performance, and reduction in the level of overshoot. Overall, these algorithms contribute to achieving the project's objectives by enhancing accuracy, improving efficiency, and reducing PAPR in the UFMC system.
