Description

A novel construction of 16-quadrature amplitude modulation (QAM) near-complementary sequences with low peak-to-mean envelope power ratio (PMEPR) in orthogonal frequency division multiplexing (OFDM) systems. The proposed 16-QAM nearcomplementary sequences can be constructed by utilizing novel nonlinear offsets, where the length of the sequences is n = 2m. The family size of the newly constructed 16-QAM nearcomplementary sequences is 8 × (m!/2) × 4m+1, and the PMEPR of these sequences is proven to satisfy PMEPR ? 2.4.
