Abstract

An integer frequency offset (IFO), in orthogonal

shift of the sub-carrier indices in the frequency domain.IFO

is challenging and expensive. Therefore, IFO is estimated and

to be relaxed, thus reducing system cost. For applications

wide frequency range access, careful RF design may be

approach for IFO estimation with reduced power consumption

reduces computational cost, while a multiplierless technique and

while maintaining a good accuracy. The novel method is shown

achievable bound. In fact, performance is significantly better

When implemented for IEEE 802.16-2009, the proposed method

FPGA devices. The method is applicable to IEEE 802.11 and

IEEE 802.22.
