摘要： A receiver in an impulse wireless communication. The receiver (300) includes a pulse-pair correlator (304) that receives a signal (316) and divides it into two signals for paths. One of the signals is input to signal multiplier (312) while another signal is delayed by a delay unit (310). The signal multiplier (312) multiplies the received signal (316) by a delayed signal (318). An integrator (314) integrates an output signal (322) over a designated period of time. An adding module (306) sums an output signal (324) from the integrator (314). An acquiring module (308) compares an summing-up output (326) from the adding module (306) with a predetermined threshold value to detect the existence of a transmitting-standard preamble.

摘要： 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 delayed pulse caused by the multipath delays from a main pulse 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.
