<p>A correlator array and a realization method thereof are provided by the present invention. The correlator array de-spreads Code Division Multiple Access (CDMA) signals received by antennas in parallel by an adder array composed of K/2 complex adders, and spreading factors of the CDMA signals are halved for each iteration. Since the present correlator array is a parallel array, each iteration can be simultaneously performed for multiple CDMA signals, or the same symbol of different users or different paths, and an array having K/2 adders only needs 2N/K periods on average to complete de-spreading of a CDMA symbol with spreading factor N. Therefore, the correlator of the present invention has high processing speed, which achieves high speed de-spreading correlation and improves the efficiency of the de-spreading correlation.</p> |
