OFDM with Reduced PeaktoAverage Power Ratio by Multiple Signal Representation
, 1997
"... In this paper two highly effective, flexible and distortionless peak power reduction schemes for Orthogonal Frequency Division Multiplexing (OFDM) with low amount of additional complexity and almost vanishing redundancy are presented. The schemes work with arbitrary numbers of subcarriers and signal ..."

and signal sets. The first approach generates a set of several alternative multicarrier signals and selects that transmit signal with the lowest peak power value. The second method optimally combines partial transmit sequences to minimize the peaktoaverage power ratio (PARcoefficient) . The schemes
A Systematic Approach to PeaktoAverage Power Ratio in OFDM
 in OFDM”, SPIE’s 47th Meeting
, 2001
"... OFDM multicarrier systems support high data rate wireless transmission using orthogonal frequency channels, and require no extensive equalization, yet offer excellent immunity against fading and intersymbol interference. The major drawback of these systems is the large PeaktoAverage power Ratio ( ..."

PeaktoAverage Power Ratio (PAR) Reduction for Acoustic OFDM Systems
"... Abstract—Orthogonal frequency division multiplexing (OFDM) is an appealing modulation scheme for highrate underwater acoustic communications which are challenged by multipath propagation. However, it has a drawback in the large peaktoaverage power ratio (PAR). Techniques for PAR reduction have be ..."

Convex Analysis
, 1970
"... In this book we aim to present, in a unified framework, a broad spectrum of mathematical theory that has grown in connection with the study of problems of optimization, equilibrium, control, and stability of linear and nonlinear systems. The title Variational Analysis reflects this breadth. For a lo ..."

Just Relax: Convex Programming Methods for Identifying Sparse Signals in Noise
, 2006
"... This paper studies a difficult and fundamental problem that arises throughout electrical engineering, applied mathematics, and statistics. Suppose that one forms a short linear combination of elementary signals drawn from a large, fixed collection. Given an observation of the linear combination that ..."

. This paper studies a method called convex relaxation, which attempts to recover the ideal sparse signal by solving a convex program. This approach is powerful because the optimization can be completed in polynomial time with standard scientific software. The paper provides general conditions which ensure
1 A New PeaktoAverage PowerRatio Reduction Algorithm for OFDM Systems via Constellation Extension
"... Abstract — Peaktoaverage powerratio (PAPR) reduction for OFDM systems is investigated in a probabilistic framework. A new constellation extension technique is developed whereby the data for each subcarrier are represented either by points in the original constellation or by extended points. An op ..."

Joint Reduction of PeaktoAverage Power Ratio and OutofBand Power in OFDM Systems
"... Abstract—The high peaktoaverage power ratio is a major drawback of OFDM systems. Many PAPR reduction techniques have been proposed in the literature, among them a method that uses a subset of tones that do not carry any data, but are modulated such that the PAPR of the resulting time domain signal ..."

"... Abstract An interleaver based technique for improving the PeaktoAverage Power Ratio (PAP) of an orthogonal frequency division multiplexing (OFDM) signal is presented. For this technique, K1 random interleavers are used to produce K1 permuted sequences from the same information sequence. PAPS o ..."
