Abstract
There is provided a selective calling radio-receiver including (a) a demodulator demodulating a received selective calling radio signal, (b) a waveform-shaper shaping waveform of a demodulation signal transmitted from the demodulator, (c) a data-receiving signal generator generating a data-receiving signal which is in synchronization with the modulation signal having a waveform having been shaped by the waveform-shaper, and which has a plurality of pulses per a symbol term, (d) a data-receiver receiving the demodulation signal at every pulse of the data-receiving signal, (e) a sign discriminator discriminating a sign of received data at every symbol, based on data having been received in the data-receiver, and (f) a processor processing the received data a sign of which has been discriminated by the sign discriminator. The selective calling radio receiver ensures receiving a signal without an error even in an overlapping area where selective calling radio signals transmitted from a plurality of base stations overlap one another in a common service area.
