Acquisition of a gated pilot
Abstract:
Systems and techniques to acquire a gated pilot signal by searching for a first gated pilot signal, deriving timing information from the search for the first gated pilot signal, and searching for a second gated pilot signal using the timing information. This can be implemented in a variety of fashions including a receiver with a searcher configured to generate a bit sequence, a correlator configured to correlate a received signal with the bit sequence, and a processor configured to detect a first gated pilot signal as a function of the correlation, derive timing information from the first gated pilot signal, and detect a second gated pilot signal by using the timing information to control the bit sequence generated by the searcher.
