Detailed Documentation
To address the high peak-to-average power ratio (PAPR) issue in OFDM systems, we propose an improved clipping algorithm. This technique effectively reduces PAPR by constraining the amplitude of peak signals through deliberate distortion. The implementation involves sampling and quantizing the input signal, followed by clipping samples that exceed a predefined threshold using conditional amplitude limiting. Key operations include real-time amplitude detection and nonlinear signal processing, which can be implemented using comparison operators and piecewise functions in digital signal processors. By controlling signal power distribution through this clipping mechanism, the algorithm enhances system performance and stability while maintaining acceptable bit error rate levels. The clipping threshold can be dynamically optimized based on system requirements using adaptive algorithms.
