Abstract:
1. A method of operating a wireless network comprising at least one base transceiver station and at least one wireless networking device, the method comprising recovering a baseband signal in at least one of the base transceiver station and the wireless networking device by: sampling a received training sequence at a relatively low number of times during each estimated training symbol interval to obtain a relatively low number of samples for each estimated training symbol interval; selecting a contiguous subset of the relatively low number of samples; obtaining a first derivative associated with the subset; multiplying the first derivative by an expected data symbol to obtain an error signal for the training symbol interval; accumulating error signals from successive training symbol intervals to form an accumulated error signal; using a first portion of the accumulated error signal to adjust which of the relatively low number of samples are to be included in the contiguous subset in connection with processing a subsequent training symbols; and using a second portion of the accumulated error signal to determine a likely position of a location of maximum eye opening to estimate the timing phase from the training sequence.
