Abstract
A communication system includes a modulating circuit to increase the amount of information to be transmitted, a transmitting apparatus capable of easily generating a desired waveform even for any very short wavelets, a receiving apparatus capable of easily separating wavelets even if the intervals thereof are narrow. The modulating circuit includes clock generating, transmission signal generating, control signal generating, delay and wavelet generating parts. The clock generating part generates a clock signal at predetermined time interval 'Tp'. The transmission signal generating part generates a transmission signal at interval 'Tp'. The control signal generating part outputs a control signal of a predetermined duration based on the clock signal. The delay part generates the control signal as a delay signal that has been delayed by a delay amount based on the transmission signal. The wavelet generating part generates a wavelet at the generation timing of the delay signal.
