An impulse radio ultra-wideband (IR-UWB) transceiver with digitalized multipulse position modulation (D-MPPM) is proposed for high-data-rate, low-power, and short-range communication. 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 modulation schemes at the same clock frequency, which results in 4.28-dB link margin enhancement compared to bi-pulse position modulation (BPPM). Also, the technique makes it possible to design a clockless receiver, which allows more compact and power efficient design. Thus, it can achieve 500 Mb/s with 27.7-mW power consumption for Rx and 7 mW for Tx and the radio range of 1-5 m.
