Abstract

The IEEE 802.16e OFDMA mode is seen as the mobile extension for metropolitan area networks. The goal of the paper is to design an estimation and compensation scheme of both carrier frequency offset (CFO) and sample clock off-set (SCO). The estimations are performed in the frequency-domain based on an interpolation between the pilots located in two successive OFDMA symbols within the DE burst. It is shown that the estimated values derived from a DE burst can be used to pre-compensate the upcoming UE burst. Due to the limiting inter-carrier interference (ICI), the compensation of the CFO is performed in time-domain. On the contrary a frequency-domain compensation of the SCO is sufficient
