In this thesis we study Impulse-Radio Ultra-Wide Band (IR-UWB), a physical layer radio technology offering many features that make it a promising choice for future short-range wireless networks. The challenges in such networks are many, ranging from the co ...
Reliability of any communication technology, such as wireless channels, can be measured by the probability of incorrect decoding of a sent message. The lower is this probability the more reliable is the technology. The main problem in wireless communicatio ...
Low power impulse radio-ultra wide band(IR-UWB) receivers have potential application in the area of wireless sensor networks. In this paper the possibility of super-regenerative receivers for pulse detection is demonstrated. The super-regenerative receiver ...
The paper aims at exploring advantages and drawbacks of using high-frequency inductive links to transmit power wirelessly to implanted biosensors. A system with an external transmitting coil located into a skin patch and a receiving coil embedded into a fu ...

Non-coherent energy-detection receivers are an attractive choice for IEEE 802.15.4a networks. They can exploit the ranging capabilities and the multipath resistance of impulse-radio ultra-wide band (IR-UWB) at a low complexity. However, IEEE 802.15.4a rece ...
Energy-detection receivers are appealing to IEEE 802.15.4a low data-rate networks because of their low complexity. With a reasonable energy consumption, these receivers can exploit the ranging capabilities and multipath resistance of impulse-radio UWB (IR- ...
The invention concerns a wireless data communication method, wherein a transmitter device (2) having a first broadband antenna (27) transmits ultra wideband coded data signals to a receiver device (3) having a second broadband antenna (37) for receiving th ...
This thesis treats the topic of chaos based broadband communication schemes, with particular emphasis on the statistical analysis and optimization of such schemes. The work is motivated by the recent advances in nonlinear system theory suggesting advantage ...
In this study, synchronization state of the coupled chaotic circuit is investigated when a sinusoidal input signal is added by both of computer simulations and circuit experiments. It is confirmed that the synchronization state changes by the values of the ...
