<p>Disclosed is a phase synchronous type maximum likelihood decoder for memorizing in a memory N number of transmit data series possibly transmitted from transmit side, for adjusting a phase of a partial series of transmit data series transmitted from the transmit side on the basis of the partial series memorized in the memory, for calculating a likelihood for the partial series transmitted from the transmit side on the basis of the partial series memorized in the memory and the partial series having adjusted phase, for comparing N number of calculated likelihood and for selecting a partial series having the maximum likelihood from the memory, thereby, the satisfactory operation in the low S/N ratio can be realized and the satisfactory phase tracking characteristics can be obtained.</p> |
