Optimizing PAPR in Multi-Antenna OFDM Systems Using PTS Algorithm

Problem Definition

Problem Description: The high peak-to-average power ratio (PAPR) in orthogonal frequency-division multiplexing (OFDM) systems, especially in multi-antenna systems, poses a significant challenge in communication systems. This high PAPR leads to spectral regrowth, intermodulation distortion, and reduces the overall efficiency of the system. The traditional methods to reduce PAPR in single antenna systems may not be as effective in multi-antenna systems. Therefore, there is a need to design and implement a Partial Transmit Sequence (PTS) algorithm specifically tailored for multi-antenna OFDM systems to reduce the PAPR effectively. By optimizing the PTS algorithm for multi-antenna systems, it is expected to achieve a significant reduction in PAPR, leading to improved signal quality, spectral efficiency, and overall system performance.

Proposed Work

In this research project titled "A Partial Transmit Sequence (PTS) Algorithm Design to achieve Peak to Average Power Reduction (PAPR)", the focus is on addressing the high peak-to-average power ratio (PAPR) in orthogonal frequency-division multiplexing (OFDM) systems, especially when multiple antennas are involved. The project aims to study the partial transmit sequences (PTS) method, known for PAPR reduction in single antenna systems, and adapt it for multi-antenna OFDM systems. The research will involve utilizing modules such as Basic Matlab, Seven Segment Display, Energy Metering IC or Module, Induction or AC Motor, and implementing PAPR reduction using PTS algorithm. The study falls under the categories of Digital Signal Processing, M.Tech | PhD Thesis Research Work, MATLAB Based Projects, and Wireless Research Based Projects, with subcategories including PAPR Reduction, MATLAB Projects Software, OFDM based wireless communication, and WSN Based Projects.

The project's performance will be evaluated based on the number of errors in the signal and the calculated PAPR reduction achieved through the PTS algorithm.
