On the analysis of peak-to-average ratio (PAR) for IS95 and CDMA2000 systems
Peak-to-average ratio (PAR) of a signal is an important parameter to a linear amplifier because it determines the backoff factor needed to be applied to the amplifier in order to avoid clipping and hence spectral regrowth. In this paper, we analyzed the PAR of the downlink direct code-division multiple-access (DS-CDMA) signal for the IS-95 (2G) and the CDMA2000 (3G) systems. Both the single-car...
متن کاملPeak to Average Power Ratio Reduction in Single Carrier OFDMA Systems
Abstract: Single carrier frequency division multiple access (SC-FDMA) which utilizes single carrier modulation at the transmitter and frequency domain equalization at the receiver is a technique that has similar performance and essentially the same overall structure as those of an OFDMA system. One prominent advantage over OFDMA is that the SC-FDMA signal has lower peak-to-average power ratio (...
متن کاملProcessor friendly peak-to-average reduction in multi-carrier systems
In this paper a computationally efficient method of reducing the peak-to-average ratio of an OFDM system is presented. Today there exist many excellent peak-to-average reduction schemes; they are however mainly focused on maximum peak reduction, not on moderate computation cost. The proposed method is based on a tradeoff between computation cost and peak reduction performance. The method is als...
متن کاملReducing the peak to average power ratio in OFDM systems
High peak to average power ratio of the transmit signal is a major drawback of OFDM systems. After defining the PAPR and analyzing its statistical properties, some of the most representative PAPRreduction techniques available in the literature are reviewed in detail. Several methods have been proposed to reduce the peak power of OFDM signals. In this paper the effectiveness of some recently pro...
