Abstract

Spectrally efficient frequency division multiplexing (SEFDM) is a multi-carrier signalling format, which has a higher spectral efficiency than conventional orthogonal frequency division multiplexing (OFDM) signals. This work presents preliminary investigations into the use of power allocation for SEFDM. In this method, different subcarriers within the same SEFDM symbol are allocated different power levels. Results show that such power allocation is beneficial to SEFDM detection, with a particular case studied here of the suboptimal fixed sphere decoder (FSD) detector. The investigated method results in a drastic complexity reduction compared to FSD without power allocation for the same error performance.
