A new interference cancellation arithmetic of space-time coding system

Space-time code is a kind of antifading techniques discussed drastically in recent years. The paper focuses on the field of space-time block coding antiinterference technique. After introducing the fundamental concept of interference cancellation and the two-step interference cancellation method used usually, the paper submits a new arithmetic, which is unselective repeated feedback interference cancellation (URF-IC) arithmetic. The arithmetic can achieve the performance of two-step interference cancellation technique while its complexity of operation is lower.
