Statistical distributions of instantaneous power and peak-to-average power ratio for single-carrier FDMA systems

This paper analyzes the distributions of instantaneous power and peak-to-average power ratio (PAPR) for single-carrier frequency-division multiple-access (SC-FDMA) signals, where localized FDMA (LFDMA) and interleaved FDMA (IFDMA), as well as a block-interleaved FDMA (B-IFDMA) are considered as a part of the discrete Fourier transform (DFT)-precoded orthogonal frequency-division multiple access (OFDMA) systems adopted in the recent mobile communications standard. Comparisons of analytical and simulation results show a good match in terms of both the measures, which confirms the validity of the analytical framework developed in this work.
