Abstract:
A selective calling radio-receiver comprising:(a) a demodulator demodulating a received selective calling radio signal;(b) a waveform-shaper shaping waveform of a demodulation signal transmitted from said demodulator;(c) a data-receiving signal generator generating a data-receiving signal which is in synchronization with said modulation signal having a waveform having been shaped by said waveform-shaper, and which has a plurality of pulses per a symbol term;(d) a data-receiver receiving said demodulation signal at every pulse of said data-receiving signal;(e) a sign discriminator discriminating a sign of received data at every symbol, based on data having been received in said data-receiver; and(f) a processor processing said received data a sign of which has been discriminated by said sign discriminator.
