Title (EN) DEMODULATOR AND DEMODULATION METHOD
(FR) DÉMODULATEUR ET PROCÉDÉ DE DÉMODULATION
(JA) 復調器および復調方法
Abstract: front page image
(EN)The objective is to demodulate a phase-modulated signal with a circuit that consumes little power and that has a small surface area. The modulator demodulates an N-value (where N is an integer 2 or greater) phase-modulated reception signal (25), and is equipped with a reference signal generator (11) that generates a reference signal (24) that has the same frequency as the carrier wave relating to the reception signal (25) and is also successively phase modulated corresponding to all of the N values within one data symbol period, a comparator (12) that compares the reception signal (25) and the reference signal (24), and a decoder (13) that demodulates the reception signal (25) based on the result of the comparison by the comparator (12) (figure 1).
(FR)
(JA) 本発明は、位相変調した信号を低消費電力、省面積の回路で復調することを目的とする。N値(Nは2以上の整数)位相変調された受信信号25を復調する復調器であって、受信信号25に係る搬送波と同一の周波数を有すると共に1データシンボル期間内においてN値の全てに対応して順次位相変調した基準信号24を生成する基準信号生成器11と、受信信号25と基準信号24とを比較する比較器12と、比較器12の比較結果に基づいて受信信号25を復調するデコーダ13と、を備える(図1)。
