AI Article Synopsis
- Implant-to-air ultra-wideband communication systems are suitable for neural recording due to their efficiency and ability to transmit data at high rates.
- The paper explores the performance of a wireless link for neural recordings using a biologically realistic model and proposes an enhanced fifth-derivative Gaussian pulse for various modulation techniques (BPSK, OOK, DPSK).
- With the need to monitor over 512 electrodes—each requiring about 800 kb/s—it's crucial to achieve a data link exceeding 400 Mbps to ensure high-resolution neural response monitoring.
Article Abstract
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.
