Apparatus and method for estimating maximum likelihood sequence using optimum sampling phase |
摘要 |
A sampling phase calculating part calculates a complex cross-correlation function; of a part corresponding to a training sequence of an equalizer of each sequence with respect to individual sample value sequences i of a reception signal y(t) which are sampled in a plurality of different sampling phases and selects a sampling phase where the absolute value of the complex cross-correlation functions is maximized, then selects a sampling phase tau s where the bit error rate is minimized according to a calculation based on the above selected sampling phase. A sampling processing part samples the reception signals y(t) in the sampling phase tau s for use in obtaining estimated values E of a transmission symbol sequence in a Viterbi algorithm processing part (130) and a transmission line estimating part (140), thereby to obtain a transmission symbol sequence with an improved bit error rate and higher accuracy.
