关键词:正交频分复用 HFC 网 限幅噪声 误码率-Abstract :Theoretical analysis is presented for the BER performance of hybrid AM/ OFDM system in the pres2
ence of clipping impulse and Gaussian noise ,and the OFDMBER has been compared with that of the single2car2
rier AM/ QAM system1It is found that ,due to the dilution effect of the subchannels ,OFDM is better than single2
carrier QAM in terms of the ability to resist chipping impulse noise interference1
Key words :OFDM HFC network clipping noise BER Platform: |

Description: This M Code simulate the effects of clipping and filtering on PAPR reduction in OFDM-based wireless standard.Also the performance of BER versus SNR of original OFDM signals with PAPR reduction based on clipping and filtering schemes over AWGN channel is evaluated.
The simplest and most widely used technique of PAPR reduction is to basically clip the part of signals that are outside the allowed region.Clipping methode introduces both in band distortion and out of band radiation into OFDM signals which degrades the performance including the BER and spectral efficiency.Filtering can reduce out of band radiation after clipping although it can not reduce in-band radiation distortion.However, clipping may cause some peak regrowth so that the signal after clipping and filtering will exceed the clipping level at some point.To reduce peak regrowth a repeated filtering and clipping operation can be used to obtain a desirable PAPR at a cost of computational complexity increase.
