Direct Chaotic Communications and Active Rfid Tags for Internet of Things and Internet of Robotic Things

Abstract

The use of ultra-wideband direct-chaotic communications and radio identification tags for the organization of wireless high-speed data transmissons on the Internet of things and the Internet of robotics is considered. Prototypes and models of ultra-wideband transceivers of the 3.0-5.0 GHz range are described and presented. It is noted that these transceivers and nodes based upon them are intended for usage in sensor and active networks with arbitrary topology. It removes some of the limitations inherent for a number of other solutions for communication and identification.

Ultra-wideband chaotic radio pulse reception in the case of inter-pulse interference

“…Using such a receiver, a detection method is proposed that requires no a priori determination of the threshold H, necessary to make decision on the arrival or on the absence of the pulse in one-path channel [4]. If the channel power exceeds the power threshold H, this means the arrival of the pulse.…”

“…Noncoherent detection of chaotic radio pulses in a multipath channel is not a problem when the propagation delays of the reflected paths do not exceed the duration of the interpulse guard interval [2][3][4]. In such a case, there is actually no interpulse interference, thus, the performance of energy detection of chaotic radio pulses in the multipath channel in terms of error probability is close to that of AWGN single path channel [2,3].…”
