BCIwiki (bciwiki.com) — A one-way impulse-radio ultrawideband (IR-UWB) uplink architecture designed for high-density brain-computer interfaces (BCIs) was described in a preprint uploaded to arXiv on September 1, 2026 (arXiv: 2609.22207). The architecture integrates an implanted packet engine and free-running transmitter, a tissue-proxy channel, and a wearable mixed-signal receiver and digital baseband within a layered protocol framework.
The design targets consistency across circuit partition, waveform mapping, packet processing, and failure semantics in high-rate neural telemetry, according to the preprint by G. D. Su and Y. Mo. The 18-page paper includes 14 figures. It has not been peer reviewed and does not report hardware measurement results. No institutional affiliations were disclosed.
