Pulse signal reception device, pulsed qpsk signal reception device, and pulse signal reception method

Abstract

A pulse signal reception device of a comparatively simple configuration detects a signal sampled at an optimal clock timing for a pulse modulation signal having a signal width shorter than a symbol frequency. In this device, a time division unit () samples a data signal at a clock signal rise edge and outputs the sampled data signals to counters (-to-), respectively. The counters (-to-) count the number of High levels when the data signal becomes High level within a predetermined period, and a maximum value detection unit () outputs maximum data string information on a data string counted by a counter in which the maximum number of High levels has been detected among the counters (-to-) to a selection data judgment unit (). The selection data judgment unit () judges which data string sampled at a particular timing is to be selected as a demodulation data string.
