UWB demodulating apparatus

摘要

A demodulated signal is to be generated by use of a first detection signal detected a presence/absence of a signal according to a correlation between a reception signal PPM-modulated at a pulse interval of T and a pulse variation width of tau and the reception signal delayed with a time (T+tau), a second detection signal detected a presence/absence of a signal according to a correlation between the reception signal and the reception signal delayed with a time (T), and a third detection signal detected a presence/absence of a signal according to a correlation between the reception signal and the reception signal delayed with a time (T-tau). By thus combining a plurality of delayed detections, it is possible to obtain a UWB demodulating apparatus configured with a circuit suited for integrated circuit fabrication.
