Abstract
A technique to provide frequency offset estimation for packets transmitted during a service period allocated strictly for designated source and destination devices. The destination device obtains coarse and fine frequency offset estimation from the short and long preambles. A residual frequency offset is tracked for the data blocks and combined with the coarse and fine frequency offset to obtain a total frequency offset to apply to the data blocks. The total frequency offset value at the end of the first packet is saved and, instead of again estimating the coarse and fine frequency offset values with the short and long preambles of the second packet, the saved total frequency offset value is used as the initialization value to add to the residual frequency offset in the second packet. The saved offset value at the end of each packet becomes the initialization value for the subsequent packet.
