Abstract: Disclosed is a wireless signal receiving apparatus, and more particularly, disclosed is a parallel automatic frequency offset estimation apparatus and method for tracking a frequency offset in an early stage by calculating, in parallel, frequency offsets of a received signal. The parallel automatic frequency offset estimation apparatus includes a receiving unit to receive a data frame; and a frequency offset estimation unit to calculate, in parallel, frequency and phase deviations at different bit intervals within a particular section of the received data frame, to add together the frequency and phase deviations to obtain a first sum of the frequency and phase deviations, and to add the first sum to a frequency phase deviation calculated for each bit after the particular section in the received data frame to obtain a second sum of the frequency and phase deviations. Accordingly, transmission frequency tracking can be performed at higher speed, compared to the conventional systems in which frequency offset acquisition is carried out in stages. Also, accurate tracking of a transmission frequency is possible in an initial frame.

Abstract: Disclosed herein is a resource allocation method for providing load balancing and fairness for a dual ring. The resource allocation method includes the step of determining whether a bandwidth allocation request message is received from one of other nodes. If the bandwidth allocation request message is received, it is determined whether one or more of two rings of the dual ring fulfill a request of the bandwidth allocation request message. If the rings fulfill the request, a path is allocated to one of the rings having a lower weighted cost. A resource allocation information notification message is provided to other nodes. If the rings cannot fulfill the request, the process ends.
