The effect of unknown non-flat interference power spectral density in OFDMA cellular system


In an OFDMA network, the downlink power spectral density (PSD) is varying dynamically to support multiple access, it is quite difficult to obtain the instantaneous interference PSD through either measurements or signaling. In this paper, we evaluate the impact of unknown non-flat interference in OFDMA system. We compare the performance of three different… (More)
