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. For users located at margin of subzone, adjacent base stations send useful information in common through same channel, but in different patterns for discrimination. Scheme of multi user combined detection is adopted at receiving end, and all these useful data detections are united. The invention raises efficiency of down transmission for users located at margin of subzone, effectively. Meanwhile, the method does not use more system resources.
