Abstract: |
When each base station or sector in cellular system sends data to each user, bit interleave is inserted between encoding process and modulation process. Different interleave patterns are adopted for different base stations or different sectors. Receiving end of cellular system determines intensity of interference signal in same channel of adjacent base stations. If intensity is larger than prearranged threshold value, then multi user combined detection is carried out and interleave patterns for distinguishing different subzones are utilized. If intensity is smaller than prearranged threshold value, then single user reception is carried out. Using interleave patterns, the invention distinguishes different subzones so as to restrain influence of interference of adjacent subzones effectively. Features are: avoiding complicated scheme for managing wireless resources, and saving system overhead. |
