“…For UWB systems operating under extremely low power regulations, such as the Japanese regulations for unlicensed use of UWB systems, use of a PA may not be needed [96]. Commonly, PAs can constitute a large portion of the transmitter power consumption.…”

“…For UWB receivers that perform correlation (or, energy detection) operations in the analog domain, ADCs can operate at much lower rates than the Nyquist rate, as sampling per frame or symbol becomes sufficient, which faciltates the design of low power UWB receivers [118], [96]. However, such receivers commonly experience performance degradation due to circuit mismatches and reduced flexibility.…”

“…There are various existing methodologies to detect pulses in time [14,[23][24][25][26]. Most of these existing methods can be classified into two categories, a non-coherent pulse detection method and coherent-pulse detection method.…”

“…Due to the large bandwidth and narrow pulse width, the UWB radio technology offers a variety of competitive features: low probability of interception, high-resolution capability, through-obstacle penetrating property, and robustness over multipath channels. Therefore, UWB technology can be used for high-rate indoor data communications, low-rate data communication, and accurate ranging and localization [3][4][5][6].…”

“…But the complexity and cost in hardware implementation is prohibitive in many practical systems. Instead, a sliding correlator is often used to serially search for the position of received pulse [6]. More closely on the circuitlevel implementation, a two-step synchronization method based on a sliding correlator was proposed [11].…”
