As the amount of information that wireless communication devices carry increases more than ever, the importance of data transmission speed and efficiency has drastically increased. Thus, the need has emerged for high-data-rate, low-power communication. Impulse-radio ultra-wideband (IR-UWB) technology is considered a suitable candidate for such needs. The latest studies have introduced various techniques to increase data rate as well as communication range while reducing power consumption, notably analog frequency hopping (AFH), which increases communication distance by increasing pulse energy , multiband IR-UWB communication that utilizes high-order modulation techniques to obtain the Gb/s data rate -, and digitalized multi-pulse-position modulation (D-MPPM)  to mitigate the dependence of the data rate on the symbol period for low-power high-speed communication. However there is still room to achieve lower power, while maintaining Gb/s speeds, and proper radio-range communication. This work proposes several techniques to achieve Gb/s data rates while maintaining tens of mW of power consumption and a few meters of communication range. Firstly extended multi-pulse-position modulation (E-MPPM) is proposed to increase data rate, secondly a high-conversion-gain cross-coupled envelope detector is proposed for improving the sensitivity and finally, a new digital frequency-hopping (DFH) technique is proposed to increase radio range by increasing pulse energy.
