“…In (Gautier et al, 2008), PAPR reduction for WPM based multicarrier systems is studied using different pulse shapes based on the conventional Daubechies wavelet family. Simulation results presented in this work show that the employment of wavelet packets can yield notable PAPR reductions when the number of subchannels is low.…”

“…Simulation results presented in this work show that the employment of wavelet packets can yield notable PAPR reductions when the number of subchannels is low. However, to improve PAPR, the authors in (Gautier et al, 2008) increase the wavelet index of the conventional Daubechies basis functions which results in an increased modulation complexity. In , two types of partial transmit sequences (PTS) methods are applied to reduce PAPR in WPM systems.…”

Wavelet Packet based Multi-Carrier Modulation (WPMCM) offers an alternative to the well-established OFDM as an efficient multicarrier modulation technique. It has the advantage of being a generic transmission scheme whose actual characteristics can be widely customized to fulfill several requirements and constraints of advanced communication systems. In the last decades wavelets have been favorably applied in signal and image processing fields but only recently have they attracted the attention of the telecommunication community. A lot of research questions remain to be addressed before the novel WPMCM can be used in practice. One of the major concerns is the performance of WPMCM transceivers under time synchronization errors. This is important because WPMCM symbols overlap in the time domain. In this paper, we analyze the interference in WPMCM transmission caused by the time synchronization errors. The expressions for Inter Carrier Interference (ICI) and Inter Symbol Interference (ISI) in WPMCM transmission are derived and then through simulation studies, the ability of wavelet-based systems to cope with time synchronization errors is evaluated.

“…The PAPR is a random variable, as the symbols arrive randomly at the modulation input. To study this measure, several researchers have analysed the distribution law for different particular modulation bases: the Fourier basis [8], the wavelet basis [9], the wavelet packet basis [10] and the discrete cosine transform (DCT) [11]. Others have studied the PAPR based on the Fourier modulation basis, using different waveforms, such as the square root raised cosine (SRRC) [12], the isotropic orthogonal transform algorithm (IOTA) [13], the extended Gaussian functions (EGF) and other prototype filters in the PHYDYAS project [14] for the filter bank multi-carrier (FBMC).…”

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 derive a general approximate expression for the cumulative distribution function (CDF) of its PAPR, for both finite and infinite integration time. These equations allow us to directly find the expressions of the PAPR distribution for any particular functions and characterize the behaviour of the PAPR distribution associated with different transmission and observation scenarios. In addition to that, a new approach to formulating the PAPR reduction problem as an optimization problem, is presented in this study.
