A maximum likelihood sequence estimator (100) implemented to cope with an intersymbol interference from a single symbol employs a necessary channel impulse response estimation vector (H) of two components (H(0), H(1)) for a decision to estimate a maximum likelihood sequence. A channel impulse response estimator (101) implemented to estimate a channel impulse response in consideration of intersymbol interferences from up to two symbols outputs a channel impulse response estimation vector (h) of three components (h(0), h(1), h(2)). The three-component vector (h) is input to a converter (102), where it is converted into the two-component vector (H) to be output to the maximum likelihood sequence estimator (100). <IMAGE> |
