<p><P>PROBLEM TO BE SOLVED: To provide a repeated signal detection method for an MIMO system. <P>SOLUTION: The method includes an arithmetic step of searching an antenna with the highest receiving signal reliability from a plurality of antenna candidates in the k-th detection layer by the use of an arithmetic parameter computed based on maximum posterior probability algorithm, and storing, with respect to the searched antenna, S paths of paths having the maximum posterior probability as survival paths, in which when k is 1, the arithmetic parameter is an initialized arithmetic parameter, and when k is larger than 1, the arithmetic parameter is an arithmetic parameter updated according to the detection result of the k-1-th detection layer; an antenna deletion step of updating the arithmetic parameter according to the arithmetic result, and deleting the antenna with the highest receiving signal reliability from the antenna candidates; and a repeating step of repeating both the steps until all the antenna candidates are deleted. The first survival path having the maximum posterior probability in the final detection layer is taken as a final detection result. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
