Abstract: A BS digital broadcast receiver having no 8PSK-demapper and a less number of delay circuits for Trellis encoding. A QPSK baseband signal based upon a reception signal point position of an absolute-phased baseband demodulation signal is Viterbi-decoded by a Viterbi-decoder 6. An output of the Viterbi-decoder is convolution-reencoded by a convolution encoder 7. Upper four bits of phase error data are searched from a phase error table 31 for carrier reproduction in accordance with a phase difference between 0 degree and a phase of a phase error detection reception signal point position. The upper four bits are delayed by delay circuits 81 to 84 by a total sum of a time taken to Viterbi-decode and a time taken to convolution-encode. The delayed outputs are demapped by a demapped value conversion circuit 9. A code TCD2 determined from the demapped output and convolution encode output is output as an MSB of a Trellis 8PSK decode output from an MSB code judging/error detecting circuit 10.
