Analog Radio-over-Fiber (a-RoF) has been the subject of increased interest in relation to next-generation optical networks due to its spectral efficiency and lower deployment cost. Nonetheless, some complexity arises from electro-optical conversion of the information signal due to the non-linear characteristic of the modulator's transfer function which causes inter-channel interference and poses a...
This paper is focused in the domain of peak to average power ratio (PAPR) reduction of orthogonal frequency division multiplex (OFDM) signals. Combination of partial transmit sequences (PTS) and simplified clipping and filtering with bounded distortion (SCAFBD) is proposed. The first mentioned method is distortionless, but needs to transmit a side information in every OFDM symbol. The second method...
The major disadvantage of orthogonal frequency division multiplex (OFDM) is the high peak to average power ratio (PAPR) of the transmitted signal. The main idea of this paper is to use a combination of two appropriate methods. First is the distortionless method using data interleaving. Second is the distortion method of repeated clipping and filtering. This combination expects better PAPR reduction...
