Abstract
An apparatus for detecting uplink ranging codes includes a first transform unit for transforming data received from a mobile station to generate first outputs; a cross-correlation unit for comparing the first outputs with possible ranging codes to generate second outputs; a screening unit for selectively passing the second outputs representing parts of the received data that match the possible ranging codes; a second transform unit for transforming the second outputs from the screening unit to generate third outputs; and a detection unit for detecting the ranging codes for the received data based on the third outputs.
