Closed-form approximations of the peak-to-average power ratio distribution for multi-carrier modulation and their applications
The theoretical analysis of the peak-to-average power ratio (PAPR) distribution for an orthogonal frequency division multiplexing (OFDM) system, depends on the particular waveform considered in the modulation system. In this paper, we generalize this analysis by considering the generalized waveforms for multi-carrier (GWMC) modulation system based on any family of modulation functions, and we d...
متن کاملAnalysis of Multi-Carrier Transmission Based on Peak-to-Average Power Ratio Reduction Techniques
In this paper, we present the analysis of the multicarrier transmission based on peak-to-average power ratio reduction techniques based on Signal distortion technique. Multiplexing a serial data symbol stream into a large number of orthogonal sub-channels makes the multicarrier signals spectral bandwidth efficient. The performance of multicarrier modulation system over frequency selective fadin...
متن کاملPeak-to-Average Power Ratio Reduction Techniques for OFDM Signals
Orthogonal frequency division multiplexing (OFDM) has been adopted as a standard for many modern wireless applications requiring high data rate due to bandwidth efficiency, resistance to frequency selective fading and simple digital realization using IFFT/FFT operations. However, physical implementation of the OFDM system suffers from several difficulties. One of the major limitations of OFDM i...
متن کاملPeak-to-Average Power Ratio Reduction Techniques for Wavelet Packet Modulation
Multi-carrier Modulation (MCM) is a popular transmission technique for high speed data communication. In MCM, transmission is carried out in parallel on different frequencies. This technique is desirable for the transmission of digital data through the multipath fading channels. By parallel transmission of data, the deleterious effect of fading is spread over many bits, therefore, instead of a ...
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 (...
