Peak Cancellation-Based PAPR Reduction for OFDM Systems | MATLAB Simulation with CCDF, EVM, PSD, and BER Analysis
In this video, we present a MATLAB-based simulation of Peak Cancellation (PC) techniques for Peak-to-Average Power Ratio (PAPR) reduction in OFDM communication systems.
The proposed method effectively minimizes nonlinear distortion caused by high PAPR while preserving signal quality and maintaining system efficiency.
