| Abstract |
In recent years, the current global trend is the rising proportion of chronic diseases, aging population since the advances in medical technology. These events will extend demands as medical services, electronic medical records and remote care. Therefore, combining medical care with a wireless body area network and develop wearable smart devices is now the important issue. IEEE 802.15.6 Task Group took nearly five years to develop IEEE 802.15.6 Wireless Body Area Networks (BAN) this standard, in response to low-cost, low-power and focus on the various factors of human characteristics, making these wireless sensor can be wear or embedded in the human body, to achieve the purpose of medical care.
In this thesis, we study on the algorithm design of baseband signal, and analysis the simulation result. At the receiver, designing the algorithm including the packet detection, energy detection and down-sampling, carrier frequency offset estimation and compensation, timing synchronization, and demodulation. The system performance after quantizing is 4dB better than the receiver sensitivity we expected. After finishing the algorithm design of the transceiver, we implement the baseband signal circuit by using Verilog Code. |
