ABSTRACT:
This invention is a method for preamble detection with estimation of UE timing advance (TA) and channel quality information (CQI) which uses a sliding window to detect the preamble and estimate user timing advance and channel quality information. The window length is set to the cyclic prefix length of data transmission. A preamble detection threshold is computed semi-analytically according to noise sample statistics.
