ABSTRACT:
A digital radiocommunication receiver includes a demodulation device for a one-symbol unit for detecting a received signal in a unit of one symbol and for outputting a received bit sequence. The demodulation device includes a maximum likelihood sequence estimation for outputting a received bit sequence from a received signal sequence concerning a plurality of symbols. A sync word detecting device determines the detection or nondetection of a sync word from the received bit sequence outputted from the demodulating device for a one-symbol unit. A timing of the bit sequence is made to coincide with a timing of the bit sequence outputted from the demodulating device involving the maximum likelihood sequence estimation. A synchronization controlling device determines a timing of a received frame and controls, as required, a transmission timing using information on the sync word detection. A received information extracting device extracts received information from an output of the demodulating device involving the maximum likelihood sequence estimation.
