Abstract: |
The invention is a method and structure for enhancing the downstream frequency duplex efficiency of honeycomb zones which belongs to frequency distribution technology field of honeycomb zones in the wireless communication, the character lies in: the original distribution method whose frequency duplex coefficient is 3and 4 is improved, part of or all adjoined zones use the same frequency in the downstream direction, in the new method, the base station sends data to each user, there has a bit interweaver between the coder and modulator, thus the zones with the same frequency may use different interweaved pattern. At the mobile station side for receiving data, selects if carries on code multi-user detection according to the intensity of the channel disturbance, the single user detecting method to demodulate and decode in the weak channel disturbance; the code multi-user detection method to demodulate and decode the data in the strong channel disturbance. |
