ABSTRACT:
A demodulator performs both synchronization and decoding concurrently by decoding a received preambleless signal according to Viterbi-decoding scheme and determining a time alignment function n(t) which indicates where the decoded sequence is located in a time period of the received signal. After converting the received preambleless signal to a received sequence in a sampling rate which is at least the predetermined symbol rate, a Viterbi decoder is synchronized with the received sequence while determining the time alignment function n(t) so that the Viterbi-decoded sequence is closest to the received sequence.
