Implant-to-air ultra-wideband communication systems are interesting for neural recording systems due to their low power consumption and high data-rates. In this paper we investigate the performance of an implant-to-air wireless link using a realistic model of the biological channel for neural recording systems. We propose an optimized fifth-derivative Gaussian pulse as a transmitted waveform for different modulations: binary phase shift keying (BPSK), on-off keying (OOK) and differential phase shift keying (DPSK). Monitoring of neural responses with high resolution in the brain requires a high data rate link as the number of electrodes is increased. Each electrode needs a data rate around 800 kb/s to support its neural channel. As we target more than 512 electrodes, we require a data link higher than 400 Mbps.
植入式到空中的超宽带通信系统因其低功耗和高数据速率而对神经记录系统具有吸引力。在本文中，我们使用神经记录系统生物通道的现实模型来研究植入式到空中无线链路的性能。我们提出一种优化的五阶导数高斯脉冲作为不同调制方式（二进制相移键控（BPSK）、开关键控（OOK）和差分相移键控（DPSK））的发射波形。随着电极数量的增加，在大脑中进行高分辨率神经反应监测需要高数据速率链路。每个电极需要约800 kb/s的数据速率来支持其神经通道。由于我们的目标是超过512个电极，因此我们需要高于400 Mbps的数据链路。
