Abstract:
It is demonstrated that the modern ultra wideband communication systems need exact synchronization of the moments of transceiving to make highlighting the information more authentic, the use of which leads to the necessity of auxiliary signals generation for the establishment the synchronization between receiver and transmitter. The development of a new method of highlighting the information without the moments of synchronization of transceiving is based on the application of a new method of coding and highlighting the information. At that the sequence of ultra wideband impulses includes the impulses going with a fixed period and they are called strong and also the impulses located between the strong ones and they are called "central". The information about the coding of "logical zero" or "logical one" by such coding method contains in temporary provision of "central" impulses as to strong ones. It is suggested to perform highlighting the information in a computer. At that, temporary delays of impulses, relative to each other, are determined on base of capstral processing and then they are transformed into the sequence of "logical zeroes" and "ones".
