An Approximate Zero IF FM-UWB Receiver for High Density Wireless Sensor Networks

A low-power frequency modulated-ultra-wideband (FM-UWB) receiver for short-range communications, capable of simultaneously demodulating multiple FM-UWB signals located at the same frequency, is presented in this paper. The proposed receiver utilizes an "ap ...

Optimization of the Data Rate of an OOK CMOS Medical Transmitter Based on LC Oscillators

Catherine Dehollain, Kerim Türe, Gürkan Yilmaz, Franco Maloberti

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 ...

Baseband and RF hardware impairments in full-duplex wireless systems: experimental characterisation and suppression

Andreas Peter Burg, Alexios Konstantinos Balatsoukas Stimming, Andrew Charles Mallory Austin, Pavle Belanovic

Hardware imperfections can significantly reduce the performance of full-duplex wireless systems by introducing non-idealities and random effects that make it challenging to fully suppress self-interference. Previous research has mostly focused on analysing ...

Switched Local Schedules for Diamond Networks

Christina Fragouli, Siddhartha Brahma, Ayan Sengupta

We consider a Gaussian diamond network where a source communicates with the destination through

n

non-interfering half-duplex relays. We focus on half-duplex schedules that utilize only local channel state information, i.e., each relay has access to its ...
