METHOD AND USER EQUIPMENT FOR ACQUIRING ORTHOGONAL VARIABLE SPREADING FACTOR CODE

摘要

A method for acquiring Orthogonal Variable Spreading Factor codes is disclosed in the invention. The method includes: descrambling the received signals (101); respectively correlating the descrambled receipt signals with the second to the 256^th Orthogonal Variable Spreading Factor codes which have a spreading factor of 256 (102); respectively accumulating the correlation values of the 255 paths of correlated signals within a length of 256 (103); respectively accumulating and averaging, within a length of a first predetermined value, the 255 paths of signals of which the correlation values are accumulated (104); respectively acquiring the energy of the 255 paths of signals accumulated and averaged, and then respectively accumulating and averaging the acquired energy of the 255 paths of signals within a length of a second predetermined value (105); and acquiring the Orthogonal Variable Spreading Factor code of the auxiliary pilot according to the energy of the 255 paths of signals which are accumulated and averaged within a length of the second predetermined value (106). The present invention can make the user equipment, which does not support Multiple Input Multiple Output, acquire the Orthogonal Variable Spreading Factor code of the auxiliary pilot according to the received signals.
