چکیده

Effect of multipath amplification is found in ultrawideband wireless communication systems with chaotic carrier, whereas information is transmitted with chaotic radio pulses. This effect is observed in multipath environment (residence, office, industrial or other indoor space). It is exhibited as an increase of signal power at the receiver input with respect to the case of free space. Multipath amplification effect gives 5–15 dB energy gain (depending on the environment), which allows to have 2–6 times longer distance range for the same transmitter power.

Ultra-Wideband Systems for Data Communications

Ultra-Wideband1 (UWB) is a radio transmission scheme that uses extremely low power pulses of radio energy spread across a wide spectrum of frequencies. UWB has several advantages over conventional continuous wave radio communications including potential support for high data rates, robustness to multipath interference and fading. We present an overview of UWB technology and its use in data comm...

Chaotic Communications with Autocorrelation Receiver: Modeling, Theory and Performance Limits

Chaotic signals are ultra-wideband signals that can be generated with simple circuits in any frequency bands at arbitrary power level. The ultra-wideband property of chaotic carriers is beneficial in indoor and mobile applications where multipath propagation limits the attainable bit error rate. Another possible application is the ultra-wideband (UWB) radio, where the spectrum of transmitted si...

Ultrawideband Wireless Sensor Networks

Application of chaos in communications, in particular, wireless communications is actively investigated since 1990s [1–5]. Direct chaotic scheme of wireless communications employs chaotic radio pulses as information carriers. This scheme was proposed in 2000 [6–7]. At that time the first experiments were made with this scheme in 900–1000 MHz range. In 2001 investigation of UWB direct chaotic sy...
