摘要：The present invention relates to a kind of devices (D types) and the

synchronous DS-CDMA receiver of associated method, and there is the synchronous codeof periodically discontinuous sending to pass through DS-CDMA transmitters. The device(D types) includes that part related operation means are used to apply part related (PC)to received data sequence and provide output correlation signal, transformationcalculations means (FFT8) are that zero application transforms to the output correlationsignal and provides complex output signal with half input, the squared absolute value ofrectangular absolute value circuit (SQUARE) is for calculating the complex output signal,Slotted non-coherent integration means apply non-coherent integration (INT) and arrivethe squared absolute value, selection approach (SELMAX) selection is maximum fromintegrated value. Therefore, the maximum value utilized, slot timing and offset estimationare determined and are synchronized.
