…This demodulation method is complex, but has good error rate characteristics. In particular, the demodulation method that utilizes the phase continuity at the transition of the modulation time interval (time slot) has an extremely good error rate characteristic compared to PSK (short for phase shift keying), and FSK that uses this method is specifically called CPFSK (short for continuous phase frequency shift keying). Another characteristic of CPFSK is that it occupies a narrow bandwidth. …

Japanese:

…この復調方式は複雑であるが，誤り率特性がよい。なかでも，変調時間間隔(タイムスロット)の変り目における位相の連続性を利用した復調方式は，PSK(phase shift keyingの略)と比べてもきわめて誤り率特性がよく，それを用いたFSKをとくにCPFSK(continuous phase frequency shift keyingの略)と呼んでいる。CPFSKは，占有帯域幅が狭いことも特徴の一つである。…
