Multiuser carrier frequency offset estimation for WiMAX periodic ranging based on OFDMA

Multiuser carrier frequency offset estimation for WiMAX periodic ranging based on OFDMA

Under WiMAX OFDMA framework,two carrier-frequency offset （CFO） estimation methods for multiuser case were proposed for periodic ranging process. The theoretical results of the two methods were derived in the case of multiuser,in which the time-domain and frequency-domain correlation properties of PN...
