So here I would like to make a small introduction of the new data transmission method we were able to develop on the basis of my institute.

Ultra Wideband Signals in Wireless Control Systems and Communication

Most of our researches were focused on two main features of a secured network - inability to detect the connection session and the security of data transmitted. We provide anonymity of connection by transmitting data under the white noise level. Thus communication session will be hidden within the natural noise background. Further, security of data transmission is achieved by time position-pulse coding of the signal and its distribution over the entire frequency spectrum. In addition, 1 bit of information is encoded as a series of 200 ultrashort pulses that are distributed between frequencies of 1Hz to 10 GHz. At the same time for the distribution of data transmission channels the additional coding is done. Each of the pulse sequences is also shifted by the time estimate that is proportional to the current value of some pseudorandom sequence that is estimated at the same time as the connection session is established.

Ultra-wideband signals are those in which the spectral width is commensurable with the central frequency The base of the ultrashort pulse is the product of the signal duration by the width of its spectrum. New World Communications project aims to develop new secure anonymous and fast wireless communication tools that will use ultra-wideband signals for private and corporate use.

It means that any kind of interference that occurs within some short frequency range will collide a small portion of pulses and receiver will still be able to receive a correct bit. At the same time for the distribution of data transmission channels the additional coding is done. Each of the pulse sequences is also shifted by the time estimate that is proportional to the current value of some pseudorandom sequence that is estimated at the same time as the connection session is established. It should also be noted that the distribution of channels is carried out with the use of time jumps, and the value of the time shift is higher than the time shift that occurs during implementation of time position-pulse modulation.

In short, application of UWB signals allows to provide:

high transmission rate and the value of the specific density of information transfer (about 1 Mbit/s/ 𝒎^𝟐)

Intrasystem electromagnetic compatibility, protection from passive interference and external electromagnetic radiation;

elimination of the negative effect of multipath signal propagation;

stealth transmission and the necessary degree of protection of information from unauthorized access

The use of noise-like signals allows you to obtain a number of advantages, which can not be achieved by traditional methods. This applies in particular increase of quality of service provided to mobile subscribers such as increasing the number of subscribers. Extension of the link band and the transition to channels with over bandwidth transmission makes it possible to have virtually unlimited increase in the number of communication channels. By pre-made distribution of signals between subscribers, their frequency and type of modulation, the communication between subscribers is done without their mutual interception and mutual interference.

At this moment of time our research group is ready to start the production and testing of transmitter/receiver prototypes. Hopefully, our campaign will go through and we will be able to do so. You may find the schemes and more solid explanation of the tech there.
