在2012年,IEEE 802.15.6 的研究團隊發表了IEEE 802.15.6 無線人體區域網路(Wireless Body Area Networks, BAN)通訊標準。此份標準宗旨為低功率、低成本的效應,且考量對於人體所造成的影響下,實行短距離的無線裝置,其可攜帶於人體上或置入人體內,提供完善的醫療照護為目的。在本論文中,將探討標準中21MHz頻段人體通訊系統的基頻端訊號處裡演算法。其中演算法的設計包括了封包偵測、取樣點偵測、子訊框邊界偵測、解展頻、訊框起始點偵測與解調變的訊號處理。並對此演算法與進行系統效能模擬,其結果符合標準所定義的接收機靈敏度規定。 最後進行撰寫Verilog硬體描述語言實現整個基頻端演算法電路。
In 2012, the research group of the Institute of Electrical and Electronics Engineers (IEEE) 802.15.6 published the specification of IEEE 802.15.6 Wireless Body Area Networks. This specification aims to achieve low power and cost. Considering the effect this specification on the human body, a wireless device with short-distance transmission is portable or can be placed in the body to supply complete medical treatment. In this thesis, we discuss the 21 MHz baseband receiver algorithms of the human body communication system in IEEE 802.15.6. The baseband receiver algorithms contain packet detection, sampling detection, subframe boundary detection, dispreading, start frame detection, and demodulation methods. Simulation experiments demonstrate that the proposed receiver algorithms achieve the requirement of the receiver sensitivity. Finally, we utilize the Verilog code to implement the circuit of the proposed baseband receiver algorithms.
