摘要
A maximum likelihood sequence estimation receiver includes a transmission line characteristic detector that detects a transmission line characteristic based on a received input signal when a training signal is received through the input terminal, an absolute value arithmetic section that performs arithmetic on absolute values of amplitude components based on the transmission line characteristic, an accumulator that accumulates the absolute values of the resultant amplitude components, a maximum value detector that detects a timing at which the cumulative output signal indicates a maximum value, and a maximum likelihood sequence estimator that performs a maximum-likelihood estimation of a received input signal using the transmission line characteristic from the transmission line detector and the timing signal output from the maximum value detector and then outputs maximum likelihood estimation data through the output terminal. This receiver can certainly and accurately judge the optimum estimation region by transmission line impulse responses using a simple algorithm, thus easily realizing its low power consumption and its simplified circuit configuration.
