Apparatus and method for sequence estimation using multi-input multi-output filter

摘要

The device which offers the presumption of the transmission sequence on the basis of the reception sequence is done and has the filter in order to obtain the sequence which is rearranged, the processor in order to process the reception sequence (101). The processor (101), using channel information and rearranging information, it processes the reception sequence. As for the said device, expedient in order to offer the information regarding the presumption error which in presumption of the transmission sequence relation is attached (109) with, using presumption error, expedient in order to calculate information (111) with, in order to offer the estimator of the transmission sequence, the filter is done and is rearranged using the sequence where you rearrange and, expedient in order to calculate information (111) being, because the presumption error value which in estimator of the transmission sequence relation is attached that tries becomes specified order, the filter you are done and in order to become the order which is the sequence value which is rearranged, you rearrange and by executing subtraction interferenceThe interference canceler in order to decrease (107) with furthermore it has. The presumption method of relating to this invention decreases degree of complicated and presumption error together.
