Simulation of Iterative Clipping and Filtering (RCF) Algorithm for Peak-to-Average Power Ratio (PAPR) Reduction in OFDM Communication Systems

In OFDM communication systems, the Iterative Clipping and Filtering (RCF) algorithm is employed to reduce Peak-to-Average Power Ratio (PAPR) through simulation. The implementation involves clipping signal peaks exceeding a predefined threshold and applying frequency-domain filtering to mitigate out-of-band radiation. This algorithm optimizes OFDM systems by reducing signal amplitude peaks while maintaining acceptable bit error rates, thereby enhancing transmission reliability and system stability. During simulation, parameters such as clipping ratio, filter length, and iteration count can be adjusted to achieve balancing between PAPR reduction and signal distortion. The simulation typically includes modules for signal generation, IFFT/FFT operations, clipping function implementation, and spectral analysis using functions like fft() and findpeaks(). This program serves as a valuable tool for researchers and engineers to make data-driven decisions in designing and optimizing OFDM-based communication systems.
