Abstract
This paper proposes the theoretical derivation method of the Shannon capacity for nonlinearly amplified uplink Orthogonal Frequency Division Multiple Access (OFDMA) in the presence of terminal mobility. In our theoretical derivation, the impact of the intercarrier interference (ICI) arising from terminal mobility as well as the multiuser interference (MUI) caused by nonlinear amplification of the mobile stations (MSs) on OFDMA signals is taken into account. Considering the fact that these interferences differ with the sub-carrier allocation methods such as localized FDMA (LFDMA) and interleaved FDMA (IFDMA), we derive the probability density function (PDF) of the instantaneous signal-to-noise-plus-distortion-plus-interference ratio (SNDIR) for each sub-carrier allocation method. Since the SNDIR is successfully expressed in the closed form, the proposed formula enables us to evaluate the Shannon capacity without conducting time consuming computer simulations.
