This paper presents a wideband signaling body channel communication (BCC) transceiver that uses the convolutional encoding method. The proposed transmitter uses the convolutional encoding method to increase the data reliability, and the modulated data are transmitted directly to a human body through a SMA cable and an electrode. In the receiver side, the oversampling phase detection clock and data recovery circuit with convolutional encoding method recovers the clock and data and increases 1.8x random data jitter tolerance (i.e., 50ns–90ns) at 10⁻⁹ BER. The proposed BCC transceiver, except for the pre-amplifier of the RX, can be realized as a synthesizable digital IP. Thus, the proposed design can be ported to different processes in a short time. The feasibility of the proposed transceiver architecture was verified by the FPGA, and no bit errors occurred over 10⁸ bits received at data rate 3.125 Mbps in transmission distance under 140 ​cm, which indicates the transceiver is very suitable for high-performance BCC applications.

本文提出了一种使用卷积编码方法的宽带信令体信道通信（BCC）收发器。提出的发射器使用卷积编码方法来提高数据可靠性，并且调制后的数据通过SMA电缆和电极直接传输到人体。在接收器端，采用卷积编码方法的过采样相位检测时钟和数据恢复电路可恢复时钟和数据，并在10 ^-9时增加1.8倍随机数据抖动容限（即50ns–90ns）误码率 除RX的前置放大器外，建议的BCC收发器可以实现为可综合的数字IP。因此，所提出的设计可以在短时间内移植到不同的过程中。所提出的收发器体系结构的可行性已通过FPGA进行了验证，在140厘米以下的传输距离内，以3.125 Mbps的数据速率接收到的10 ⁸位未发生比特错误，这表明该收发器非常适合高性能BCC应用。
