Abstract

In this work, Power Spectral Density (PSD) of different implementations of Single-Carrier Frequency Division Multiple Access (SC-FDMA) are investigated. First, a general model of spectrally shaped SC-FDMA transmission scheme is proposed. This scheme is shown to encompass different implementations of SC-FDMA including the classical Long Term Evolution (LTE) SC-FDMA waveform. Then analytical expressions of PSD are derived for both localised and interleaved FDMA using or not spectral shaping techniques based on the aforementioned general SC-FDMA system model. Finally, analytical results are validated through comparison with simulation estimated PSD.
