An IR-UWB CMOS Transceiver for High-Data-Rate Low-Power and Short-Range Communic

Abstract

An impulse radio ultra-wideband (IR-UWB) trans- ceiver with digitalized multipulse position modulation (D-MPPM) is proposed for high-data-rate, low-power, and short-range com- munication. The D-MPPM overcomes the data-rate dependence on the system clock frequency by modulating data with the time difference between the two pulses and also allows fully digital circuit-based modulation and demodulation. With this technique, the data rate is improved by a factor of 5 compared to conventional IR-UWB
