ABSTRACT:
An Orthogonal Frequency Division Multiple Access (OFDMA) device and method of correcting frequency offset in OFDMA signals computes an estimated frequency offset, which is used for producing a frequency offset-compensated mixer signal using a reference clock signal. The frequency offset-compensated mixer signal is used to produce a digital down-converted signal from an incoming OFDMA signal. The digital down-converted signal is digitally corrected for sampling errors using the estimated frequency offset.
