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 ...
Communication systems have played a key role in changing our lives as such systems help to access remote data and to transfer it to the end user when requested. Intelligent nodes, which can process and transmit information placed in a given environment can ...
Recording neural activities plays an important role in numerous applications ranging from brain mapping to implementation of brain-machine interfaces (BMI) to recover lost functions or to understand the mechanisms behind the neurological disorders such as ...
The impulse radio-ultra wide band (IR-UWB) signalling format has been an attractive mode for wireless communication in wireless sensor node system. The super-regenerative principle can be used for impulse reception for its inherent advantages. The oscillat ...

While wireless communication has become an ubiquitous part of our daily life and the world around us, it has not been able yet to deliver the multi-gigabit throughput required for applications like high-definition video transmission or cellular backhaul co ...
This paper presents techniques for increasing communication data rates for OOK modulated signals in the case the carrier frequency is generated by a cross-coupled pair LC oscillator. The proposed circuitry completely turns off the transmitter during the tr ...

We demonstrate high speed optical transmission systems using digital coherent detection at all-electronically multiplexed symbol rates of 80 and 107 Gbaud. At 107 Gbaud, we demonstrate a single-carrier polarization division multiplexed quadrature phase shi ...
The continuing demand for higher bandwidth in serial interconnects has pushed the symbol rate of differential lanes into the high-insertion-loss region of channels. Multi-level signaling such as differential PAM-4 [1] has been used to mitigate the loss of ...
