Receiver selecting either a first demodulated signal or a second demodulated signal in accordance with characteristics of a received signal

摘要

An equalizer block forming part of a receiver compensates transmission path characteristics of a baseband received signal to generate a prediction signal, and differential-logic-converts a demodulated signal generated by demodulating the prediction signal to generate a differential-logic-conversion demodulated signal. A differential- detection demodulator block differential-detects the prediction signal from the equalizer block and subsequently demodulates the differential- detected prediction signal to generate a differential- detection demodulated signal. A selector block selects either the differential- logic-conversion demodulated signal from the equalizer block or the differential-detection demodulated signal from the difference-detection demodulator block.
