Abstract
An apparatus for detecting a spread spectrum signal in a wireless signal environment includes at least one antenna for receiving spread spectrum signals, such as UMTS signals, from a signal source in the wireless signal environment. In one embodiment, a detection circuit is configured for correlating a code in signal received by the apparatus with a set of possible codes for spread spectrum signals in order to detect the existence of a spread spectrum signal. In another embodiment, a detection circuit is configured for obtaining at least one reference frame of data from a received signal. The detection circuit is further operable for correlating a segment of the reference frame with a repeated segment of at least one subsequent frame of data in order to detect the existence of a spread spectrum signal. A repeater might incorporate such an apparatus wherein the variable gain of the repeater is adjusted based upon the correlation and the detection of a spread spectrum signal.
