发明名称 Method for determining a time offset of a CDMA signal
摘要 A method is described for determining a time offset of a CDMA signal incurred during transfer. For each of a plurality of time offset estimates, the received chip sequence is multiplied with a conjugate complex scrambling code that is shifted by a number of chips according to one of the time offset estimates; the chip sequence is despreaded based on a spreading code of at least one selected data channel to produce a symbol sequence, and an estimated amplification factor is determined by summation of an amount of the symbol sequence. The maximum of the amplification factors for the time offset estimates when a selected data channel is active, or the minimum of the amplification factors for the time offset estimates when the selected data channel is not active is then determined.
