一种无线植入式神经控制信号传输的数据编码方法

文中提出了一种新的数据编码传送方法.在外部模块用脉宽调制的方法将需要传送的数据进行编码,通过BPSK调制和解调方式传送到体内模块后使用时钟检测器、时钟分频器、脉冲宽度计数器以及脉冲逻辑判决器进行解码.这样体内模块和体外模块可以工作在不同时钟,使得电路的设计和验证大为简化.该方法已经成功应用于植入式无线神经信号获取系统的板级电路中,波形测试的结果显示了该方法的可行性.

A Data Coding Method for Transmitting of the Wireless Implantable Neural Configuration Data

A new data encoding method is presented in this paper. In the external module, the configuration data is coded by a pulse-width-modulation method. When this coded signal is transmitted to the internal module through BPSK modulation and demodulation, Clock Detector, Clock Divider, Width Counter and Width Judging are used to decode the signal. This makes the internal device can fit the different clock frequencies and makes sure that the internal modules and external modules can work at asynchronous system clocks. The new coding method is shown to be successful by a wireless implantable neural signal acquisition board circuit system and the testing results.
