A Human Body Communication Transceiver Based on On-Off Keying Modulation
This paper presents an on-off keying (OOK) human body communication (HBC) transceiver design method for wireless body-area network (WBAN). The HBC channel in shield chamber by adopting floating ground experiment setup is analyzed and the optimal carrier frequency of 30 MHz is chosen. A FPGA and a direct-digital synthesizer (DDS) are applied to achieve OOK modulation in the HBC transmitter. In the receiver part, the signal is firstly filtered by a band pass filter, and then converted to voltage through a logarithmic amplifier. Finally a comparator and a clock data recover (CDR) circuit are used to recovery the data. The proposed HBC transceiver is implemented in a PCB board and validated in human body. The result shows that the transceiver can transfer 2-Mbps none return zero (NRZ) data from forearm to finger through the human body successfully.
