Bit Error Rate (BER) Performance of CLIPPING Scheme for PAPR Reduction in OFDM Systems

In OFDM systems, the Peak-to-Average Power Ratio (PAPR) problem significantly impacts system performance. The CLIPPING scheme provides an effective solution to reduce signal PAPR, thereby improving the Bit Error Rate (BER) performance. The CLIPPING method works by limiting signal amplitudes that exceed a predefined threshold. This can be implemented computationally using: - Amplitude threshold comparison algorithms - Signal magnitude normalization techniques - Hard-limiting functions that clip peaks while preserving phase information Key implementation considerations include: 1. Setting optimal clipping thresholds to balance PAPR reduction and signal distortion 2. Applying windowing functions to minimize spectral regrowth 3. Using iterative clipping and filtering to maintain signal quality The technique demonstrates particular effectiveness in scenarios requiring low-complexity PAPR reduction while maintaining acceptable BER performance in wireless communication systems.
