In a system, device, and method for selecting a channel from among a plurality of channels, a number of available channels are selected for testing. A channel quality measurement is made for each of the number of available channels. The channel having the best channel quality measurement is then selected. To make the channel quality measurements, a primary station selects a channel to be tested and also selects a secondary station with which to perform the test. The primary station transmits a control frame to the selected secondary station, including a channel identifier identifying the selected channel. Upon receiving the control frame, the selected secondary station adjusts its transmitter to the selected channel based on the channel identifier in the control frame, and transmits a reference signal on the selected channel. Meanwhile, the primary station adjusts its receiver to the selected channel and receives the reference signal from the selected secondary station. The primary station then measures the quality of the received reference signal.

In a chain of linear time-invariant operations ( ), all bias introduced between operations collectively produce a total deterministic error at the final output of the chain of operations ( ). In the present invention, truncation is used in place of rounding after each operation by simply not rounding in software. Recognizing that all the bias introduced by replacing rounding with truncation results in a single deterministic error at the final output, in the present invention the total bias ( ) is predetermined and subtracted from each data sample of the final output sequence.
