摘要： A method for allocating a plurality of spreading codes to a plurality of base stations is disclosed. After retrievably storing distances between each of the base stations and other base stations in a memory, the memory is searched for a longest distance of the distances. Based on a necessary spreading code difference and a longest spreading code shift corresponding to the longest distance, a spreading code spacing between spreading codes to be allocated to the base stations is determined. Then, spreading codes with the spreading code spacing are sequentially allocated to the base stations.
