UWB PULSE STRING GENERATING APPARATUS AND METHOD, AND DATA TRANSMITTER-RECEIVER AND METHOD USING ITS PULSE STRING

摘要

PROBLEM TO BE SOLVED: To provide an UWB (Ultra Wide Band) pulse string generating apparatus and a method, and the data transmitter-receiver apparatus using its pulse string and a method.;SOLUTION: The data transmitter-receiver comprises a random number generation part, a pulse string generation part which generates a pulse string with a random interval corresponding to a data to be transmitted by using a random number string generated by the random number generation part, a template pulse string generation part which generates a reference template pulse string for searching a start position of a received pulse string with a random interval and a pulse string corresponding to "0" signal and " 1" signal by varying pulse width, a random number string detection part which receives the pulse string with a random interval and investigates information about the start position of a random number string used for generating the received pulse string with a random interval by using the reference template pulse string, and a comparison part. The comparison part decides whether the value of the pulse string with a random interval is "0" or "1" by comparing the pulse string corresponding to "0" signal and "1" signal which is generated by using information about the start position of the random number string in the template pulse string generation part with the pulse string with a random interval.;COPYRIGHT: (C)2004,JPO&NCIPI
