The paper analyses several modulation and detection pairs for Impulse-Radio Ultra-Wideband (IR-UWB) Body Area Networks (BANs). First, transceiver architectures with and without chirp pulse compression are described. After that, exact expressions for the bit error probabilities in noise are given. At the end, numerical analysis is performed that includes performances in noise and performances in multiple...
The paper investigates chirp pulse compression as a signal dimension reduction technique in non-coherent impulse-radio ultra-wideband (IR-UWB) communications. Two common types of non-coherent IR-UWB detection are considered, energy detection of IR-UWB pulse position modulated (PPM) symbols and sample-wise differential detection of differential phase shift keying (DPSK) IR-UWB symbols, as well as a...
The paper investigates benefits of using chirp pulse compression in non-coherent Impulse-Radio Ultra-Wideband (IR-UWB) communications. Furthermore, we develop closed form expression for bandwidth and dimension of the signal after the chirp pulse compression that was lacking before. Two usual types of non-coherent IR-UWB detection are considered — energy detection of PPM-modulated symbols and sample-wise...
