The Performance of OFDM-SDMA Systems With Power Amplifier Non-Linearities
Overview Amplifier nonlinearities affect drastically the performance of Orthogonal Frequency Domain Multiplexing OFDM systems. In this paper, the effects of amplifier nonlinearities is evaluated in OFDM with Space-Division-Multiple-Access (SDMA).This paper shows that nonlinear power amplifier reduced dramatically the performance of multiple-antennas OFDM systems. The introduction of an array antenna system in the base station of a mobile communication system increases the spectral efficiency, reducing the co-channel interference and increasing the reuse factor of the systems. It helps to increase the numbers of users placed in the same spectral portion.
