Performance analysis of SC-FDMA in the presence of receiver phase noise

We study the effect of receiver phase noise (PHN) on single carrier frequency division multiple access (SC-FDMA). We show that in the case of SC-FDMA, common phase error (CPE) rotates all the symbols by a certain angle, while the higher order frequency components of PHN result in inter-carrier interference (ICI). We then study the effect of PHN on the performance of linear receivers used in the detection of SC-FDMA/OFDMA symbols. In particular, we show that the amount of ICI affecting the sub-carriers depends closely on the allocation of sub-carriers amongst different users and further show that the performance of linear receivers in the case of interleaved SC-FDMA deteriorates much more than in the case of localized SC-FDMA in the presence of receiver PHN.
