Dual Threshold Clipped DCT-PTS PAPR Reduction in OFDM.

Problem Definition

Problem Description: High peak-to-average power ratio (PAPR) is a major issue in Orthogonal Frequency Division Multiplexing (OFDM) systems, which can lead to power inefficiency and distortion in signal transmission. Traditional techniques such as Partial Transmit Sequence (PTS) have been used to reduce PAPR, but they may not be sufficient to fully address the issue. Additionally, the PAPR reduction using only PTS may not be effective in maintaining signal quality. Therefore, there is a need for a more advanced and effective PAPR reduction approach in OFDM systems to ensure both reduced PAPR values and maintained signal quality. The proposed modified Discrete Cosine Transform (DCT) clubbed PTS with dual threshold clipping approach aims to address this problem by combining DCT and PTS techniques to achieve better PAPR reduction results.

The effectiveness of this new approach needs to be verified through simulation results and compared with existing techniques to showcase its advantages in reducing PAPR in OFDM systems.

Proposed Work

The research work titled "A Modified DCT clubbed PTS PAPR reduction approach with dual threshold clipped in OFDM" focuses on addressing the high peak to average power ratio (PAPR) issue in Orthogonal Frequency Division Multiplexing (OFDM) systems, which is crucial for high-data rate transmission in wireless and wired communication. OFDM is a key technology in 4G and 5G networks due to its ability to mitigate selective fading and provide parallel transmission of orthogonal subcarriers for high data rates. The proposed approach uses a combination of Partial Transmit Sequence (PTS) and Discrete Cosine Transform (DCT) to reduce the PAPR value in the time domain OFDM signal. By implementing a double threshold clipping method, the new technique aims to efficiently cut both sections of the signal to achieve a significant reduction in PAPR. The research is carried out using the Basic Matlab software to simulate and demonstrate the effectiveness of the proposed approach.
