Abstract
我們提出一個操作在低頻帶（小於九百六十兆赫）之脈波式超寬頻收發機架構，主要使用於短距離、低複雜度以及低必v消耗之產品，如無線射頻識別卡與感應偵測網路。由於設計目標以低系統複雜度以及低成本為考量，使用最少的射頻或微波電路，幾近全數位的實現方法是可行的，以避免其他昂貴與必v需求極大之類比元件。
在本研究中，我們建立了完整的收發機模型，並將有興趣之關鍵要素，如窄頻干擾、多路徑衰減、頻率偏移、時脈抖動、類比數位轉換器之位元數與偏移以及非線性等加入系統模擬，以針對我們的設計做最佳化與利益取捨。
最後，模擬結果顯示我們所設計之收發機在短距離、低弁鈶野峇冗犑@表現令人滿意。
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.
