A Generalized Construction of OFDM M-QAM Sequences With Low Peak-to-Average Power Ratio
Zilong Wang, Guang Gong, and Rongquan Feng
TL;DR
This paper presents a generalized method for constructing OFDM M-QAM sequences that achieve low peak-to-average power ratios, unifying previous approaches and providing bounds on PMEPR.
Contribution
It introduces a new generalized construction for OFDM M-QAM sequences with low PMEPR, encompassing earlier methods as special cases.
Findings
Provides an explicit construction method for sequences
Establishes an upper bound on PMEPR for the sequences
Unifies previous constructions under a generalized framework
Abstract
A construction of -QAM sequences is given and an upper bound of the peak-to-mean envelope power ratio (PMEPR) is determined. Some former works can be viewed as special cases of this construction.
