Abstract:
1. An ultra-wideband transmitter, comprising: a delay time controller for generating and inputting a periodic pulse to a first matched filter, outputting the periodic pulse to a second matched filter when data to be transmitted are at a first level of a binary logic level, and outputting the periodic pulse to a third matched filter when the data to be transmitted are at a second level of the binary logic level, wherein the first matched filter receives the periodic pulse from the delay time controller and outputs a reference signal for data determination, the second matched filter receives the periodic pulse from the delay time controller and outputs a first data signal earlier than the reference signal by a predetermined time, and the third matched filter receives the periodic pulse from the delay time controller and outputs a second data signal later than the reference signal by a predetermined time; an adder for adding outputs of the first, second, and third matched filters and outputting the added signal; and an antenna section for receiving the added signal from the adder and radiating the received added signal into the air.
