Baseband recovery in wireless networks, base transceiver stations, and wireless networking devices may be implemented to minimize the number of timing symbols while at the same time enabling wireless devices to use a relatively low per-symbol sampling rate, so that minimal processing is required to implement the timing recovery. In one embodiment, a relatively low number of samples is taken per expected symbol interval during the training sequence. A subset of the samples is selected and processed to determine error signals for each of the samples. The error signals are multiplied by the expected symbol and summed to form an error signal. The error signal is used to adjust the set of samples that will be used and processed in connection with subsequent symbols. The error signal is also used to interpolate between available samples to infinitesimally approach the point of maximum eye opening.
