Patent ID: 8451888

Claim:
An impulse communication apparatus comprising: a modulated pulse generating part generating a modulated pulse by performing a pulse position modulation operation to data; an impulse train generating part generating an impulse train from the modulated pulse by on-off keying; and an impulse train sending part sending the impulse train generated by the impulse train generating part, wherein the impulse train generating part includes: a first part that generates a pulse; a second part that performs an AND operation on the modulated pulse and the pulse generated by the first part to generate another pulse, a period of the pulse generated by the first part being shorter than a pulse width of the modulated pulse; and a third part generating the impulse train, the pulse width of the impulse train being narrower than the pulse width of the another pulse and one pulse of the impulse train corresponding to one pulse of the another pulse, at a timing defined by the another pulse, an impulse of the impulse train being in synchronism with either the rising edge of the another pulse or a falling edge of the another pulse, wherein the third part comprises a step recovery diode, and wherein the pulse has multiple sets of a high level and a low level during one high level or low level of the modulated pulse.
