Clipping and filtering
WebJul 18, 2014 · Iterative clipping and filtering (ICF) is a widely used technique to reduce the peak-to-average power ratio (PAPR) of orthogonal frequency division multiplexing … Clipping is a form of distortion that limits a signal once it exceeds a threshold. Clipping may occur when a signal is recorded by a sensor that has constraints on the range of data it can measure, it can occur when a signal is digitized, or it can occur any other time an analog or digital signal is transformed, particularly in the presence of gain or overshoot and undershoot.

In this paper, an improved scheme of amplitude clipping & filtering method is proposed and implemented which shows the significant improvement in case of PAPR reduction while increasing slight BER compare to an existing method. Also, the comparative studies of different parameters will be covered. KEYWORDS
WebClipping and filtering is the conventional method, including hard clipping and low-pass filtering. As shown in the above figure, clipping can cause sharp corners in a clipped signal, which leads to an unwanted out-of-band emission(increased ACP). WebSep 7, 2024 · Clipping and filtering decreases the peak amplitude of the input signal to a pre-defined threshold level [30]. where, clipping level is denoted by A which is a positive …
WebThe filtering technique is designed to alleviate out-of-band distortion but cannot correct in-band distortion. Fig. 1 demonstrates the clipping and filtering process [7] [17]. WebFiltering after clipping can preserve the spectral effi- ciency and hence improve the BER performance but it can gen- erate large time-domain peaks [9]. For this reason, to reduce …
