Abstract
This work presents preliminary investigations into the use of power allocation for the multi-carrier non-orthogonal spectrally efficient frequency division multiplexing (SEFDM) signalling format. SEFDM is utilized to improve the spectral efficiency compared to conventional orthogonal frequency division multiplexing (OFDM), by violating the orthogonality condition and getting the sub-carriers closer to each other. In this paper, subcarriers within the same SEFDM symbol are allocated different power levels. Results show that such power allocation is beneficial to SEFDM from several perspectives: i) Overall system stability enhancement; ii) a drastic complexity reduction in SEFDM detector; iii) peak to average power ratio (PAPR) performance improvement.
