MATLAB Implementation of Tone Reservation via Clipping Technique

This document presents a MATLAB implementation of the Tone Reservation via Clipping technique, which addresses the Peak-to-Average Power Ratio (PAPR) challenge in Orthogonal Frequency Division Multiplexing (OFDM) systems. The implementation includes key algorithmic components such as frequency domain tone selection, iterative clipping operations, and reserved tone optimization. The Tone Reservation via Clipping method operates by allocating specific subcarriers as reserved tones in the frequency domain. The core algorithm involves applying controlled clipping to time-domain OFDM signals while compensating for distortion through adjustments to the reserved tones. The MATLAB code demonstrates this process through functions that handle signal generation, clipping threshold calculation, and iterative peak cancellation. The provided MATLAB simulation enables comprehensive testing of the PAPR reduction technique prior to hardware deployment. The code structure includes modules for parameter configuration, OFDM symbol generation, clipping noise calculation, and reserved tone updating. Key functions implement the iterative clipping and filtering process while maintaining signal quality constraints. This implementation serves as an essential resource for OFDM system designers, offering insights into practical PAPR reduction strategies. The code facilitates performance analysis of the tone reservation approach and helps identify implementation challenges through customizable parameters such as clipping ratio, reserved tone positions, and iteration counts.
