碩士 === 國立臺灣大學 === 電信工程學研究所 === 92 === We propose an impulse-radio ultra-wideband transceiver architecture operated in low band (<960MHz) for short range, low complexity, and low power applications such as radio frequency identification (RF-ID) and sensor network. Since the goal is toward low system complexity and low cost, a nearly “all-digital” implementation is feasible with minimal RF or microwave electronics, avoiding otherwise expensive and power hungry analog components. In this work, we construct the overall transceiver model and take key factors of concerns into system simulations to optimize and make trade-offs for our design, such as narrowband interference, multipath, frequency offset, jitter, A/D bits number, ADC offset, nonlinearity, and etc. Finally, the simulation results show that the transceiver we design works well for short range and low power applications.
