Abstract
A signal received by a receiving antenna is input to an UDMV through a detector, and compensation for distortion caused by multipath fading and an error correction using Viterbi decoding are simultaneously performed, obtaining demodulation data. The UDMV comprises a demodulator in which an MLSE and a Viterbi decoder are combined. Thereby, equalization for removing a line distortion and reduction in an error rate can be simultaneously performed, improving a receiving quality.
