摘要：<P>PROBLEM TO BE SOLVED: To heighten the estimation accuracy of interference replica signals while restricting the amount of arithmetic operation, thereby improving a signal-to-interference power ratio. <P>SOLUTION: In a radio communication method, where a plurality of cells respectively have one or more base stations located therein and the base stations which are each connected to a network via a wired circuit communicate with a terminal station in the cell via the wired circuit, the calculation of a high-order transmission wait queue in which interference cancellation for the entire service area is taken into consideration is not performed before transmission information is multiplied thereby, but rather an a'th order transmission signal T<SB POS="POST">i</SB><SP POS="POST">[a]</SP>is calculated by a recurrence equation while measuring signal quality, by using a matrix M<SB POS="POST">i,j</SB>which is a small scale matrix common to the values of each a, and a solution to a high-order transmission signal is acquired while restricting the amount of arithmetic operation and, when a transmission signal change amount is determined to be smaller than a threshold, the process is terminated. <P>COPYRIGHT: (C)2013,JPO&INPIT
