摘要:
A maximum likelihood decoder for decoding a code from a signal transmitted through quadrature amplitude modulation of a code including a convolutional code can decode at high speed and high accuracy with a simple hardware configuration. In the maximum likelihood decoding of the convolutional code, the metric processing is not carried out for all of the possible paths and states but a smaller number of path(s) (metric(s)) and state(s) (metric(s)) are selected in a descending order to determine survival paths.

A simplified carrier phase control apparatus used in a modem for demodulating a quadrature amplitude modulated data signal, to correct phase jitters of a carrier signal due to a 50 Hz or a 60 Hz frequency of the commercial power supply, and its harmonic wave frequency components. The carrier phase control apparatus has a predictive filter for predicting a carrier phase jitter, the predictive filter composed of band-pass filters with center frequencies of 50 Hz and 60 Hz, and a circuit where the output signals of the band-pass filters are multiplied by the coefficients and added linearly.
