Title:
PULSE TRANSMITTING DEVICE, PULSE RECEIVING DEVICE, PULSE COMMUNICATION SYSTEM, AND PULSE COMMUNICATIO METHOD
Document Type and Number:
WIPO Patent Application WO/2008/013064
Kind Code:
A1
Abstract:
A pulse transmitting device is provided to avoid interference between pulses due
to multipath influence even in a high speed pulse transmission that is typical of
a UWB by making use of a relatively simple method and to improve receiving quality. In
the device, a pulse adjusting unit (110) generates pulses in response to transmitting data,
a non-use interval setting unit (120) sets up a non-use interval where the pulses
generated by the pulse adjusting unit (110) are not transmitted on the basis of
a delay time that a delay wave caused by the multipath delays from a main wave and
takes until arriving at a communication partner. A pulse position adjusting unit
(130) adjusts a pulse position not to transmit the pulses during the non-use pulse
interval. An RF transmitting unit (140) converts the pulse, the position of which
is adjusted by the pulse position adjusting unit, to a wireless frequency band
and transmits a pulse wireless signal after the conversion to the communication partner.
