发明名称 Device for synchronizing a receiver and a transmitter in a communication system
摘要 The present invention relates to a device (D) and an associated method for the synchronization of a DS-CDMA receiver with a synchronization code being sent periodically and discontinuously by a DS-CDMA transmitter. Said device (D) comprises partial correlation calculation means (PC) for applying partial correlation to the received sequence of data and for providing output correlation signals, transform computation means (FFT8) with half inputs being zeros for applying a transform to said output correlation signals and for providing complex output signals, a square absolute value circuit (SQUARE) for calculating the square of absolute values of said complex output signals, slot-wise non-coherent integration means (INT) for applying a non-coherent integration to said square absolute values, and, selecting means (SELMAX) for selecting a maximum from the integrated values. Thus, with the maximum selected, a slot timing and a frequency offset estimate are determined for the synchronization.
