摘要 |
<p>A state estimator (40) generates a plurality of candidates of estimated desired signal sequences corresponding to the transitions of state of desired signals estimated to be received, and a plurality of candidates of estimated undesired signal sequences corresponding to the transitions of state of undesired signals sequentially. The candidates are sent to a desired signal estimator (10) and a undesired signal estimator (20), respectively. In accordance with the conversion parameters set from a channel parameter estimator (50), the estimators (10 and 20) generate an estimated desired signal and an estimated undesired signal by use of the respective candidates. An error estimator (30) subtracts a signal of the sum of these signals from the received signal and generates an estimated error signal epsilon . The state estimator (40) estimates estimated error of desired signal sequences and undesired signal sequences with respect to the generated sequence candidates. <IMAGE></p> |
