ABSTRACT:
In a digital radio communication apparatus which receives PSK modulated signal, a plurality of items of quantized data are sampled at a plurality of points including a central point, which corresponds to one of each rising edge or each decaying edge of a reproduction clock signal, points before the central point and points after the central point. The sampled plurality of items of quantized data are combined so that combined phase data is obtained for each symbol.
