IMPULSE RECEIVER, IMPULSE TRANSMITTER AND IMPULSE RADIO COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an impulse receiver which allows for simplification of circuitry, and further improvement of frequency utilization efficiency.;SOLUTION: An impulse receiver has a clock reproduction circuit 10 for reproducing a clock from a reception impulse signal indicating a reception pulse, a first phase adjustment circuit 30 for roughly adjusting the delay amount of clock, a second phase adjustment circuit 40 for generating a reproduction clock by further performing fine-tuning of the delay amount of clock subjected to rough adjustment by the first phase adjustment circuit 30, a reception bandpass filter for generating a local impulse according to the change edge of the reproduction clock, and generating a local impulse signal by passing a predetermined band of the local pulse, a detector circuit 20 for detecting the reception impulse signal in response to the local impulse signal and outputting an intermediate frequency signal, and a data reproduction circuit 50 for reproducing the data corresponding to the intermediate frequency signal, and outputting the reproduced data while latching by the change edge of the reproduction clock.;SELECTED DRAWING: Figure 13;COPYRIGHT: (C)2018,JPO&INPIT
