摘要 根据人体信道特点,以FPGA为平台设计了一种适用于电流耦合型人体通信的全数字锁相位同步提取电路。仿真和测试的结果表明,该电路具有较好的相位跟踪性能,可以达到锁定时间短、相位抖动小、锁相精度高的结果,为讨论人体通信系统的实现与传输方式提供了有效保证。 According to the characteristics of human channel,an extraction circuit of all digital phase-locked bit synchronization based on FPGA is designed,which applies to galvanic coupling Intra-body Communication(IBC).The results of simulation and test show that the circuit is suitable for phase-tracking and appears quick launching,small errors and high precision.And it is guaranteed for the implementation of IBC system.
