Ultra-Wideband (UWB) link emerges as a promising physical layer candidate for a wide range of wireless networks. In addition to the potential of very high data rate, the ultra-wide bandwidth also provides enhanced flexibility for transceiver designs with variable complexity, which is particularly suitable for networks with heterogeneous nodes. However, to establish physical communication links between...
As a high-rate alternative of impulse radio (IR) ultra-wideband (UWB) communications, analog and digital multi-carrier UWB radios with coherent detection have been introduced. In this paper, we investigate digital multi-carrier differential (MCD) modulation and demodulation schemes for UWB. In our approach, the differential encoding and decoding are carried out across multiple digital carriers in...
