Abstract :
In this paper, we evaluate a synchronization scheme for carrier frequency offset (CFO) and tuning offset (TO) in IEEE 802.16e subscriber station (SS). In addition, we integrate both inner receiver and outer receiver to evaluate the performances under SUI-4 channel. According to the simulation results, the proposed algorithms resolve CFO and TO effectively with low complexity.
