| Abstract(in English) | In mobile communication with CDMA, the switching network is constructed by orthogonal codes assigning to each user in order to distinguish one from the others. The number of distinguishable codes and the process speed are different according to the orthogonal spreading factors. We try to improve the speed of communication by changing the spreading factors of orthogonal codes according to the number of users. In this paper, we propose the effective way to change the spreading factors using tree structure. |
