| Summary: | 碩士 === 國立中央大學 === 通訊工程研究所 === 97 === The K-exponential filter is designed for peak to average power ratio (PAPR) reduction without intersymbol interference (ISI). The key point is that the frequency responses of the filter which keeps the same bandwidth can vary with different designing parameter, the origin for the name. There is a minimum PAPR corresponding to an appropriate when roll-off factor α is fixed. The simulated result shows that the maximum PAPR reduction by the filters is about 0.25 dB in OFDM system and 1 dB in IFDMA system compared with the raised cosine filter. Besides, the K-exponential filter has almost equal performance in IFDMA system but better performance in OFDM system compared with the same kind of the versatile filter.
