这个小型企业创新研究(SBIR)第一阶段项目旨在展示在保持超低功耗的同时，通过医疗植入物通信服务(MICS)频段实现高效的高吞吐量视频广播系统的可行性，用于相机药丸和微型机器人技术。目前的相机药丸设计具有相对较低的数据速率和较高的功耗。拟议的系统旨在显著改进现有系统的规格。这项研究的智能优点在于设计了一种用于相机片应用的集成电路，该集成电路结合了先进的数字宽带技术，如正交频分复用(OFDM)、低密度奇偶校验码(LDPC)和分集技术，并结合了最先进的VLSI架构设计。该技术的主要预期优势包括：超高吞吐量、超低功耗和紧凑型发射机、低成本发射机、远距离规范、实时传输、准确的同步算法、频率带宽效率和干扰避免。此外，如果这种高通量系统与其他低速率设备一起使用，剩余的吞吐量可以自动转化为额外的节能。该项目更广泛的影响/商业潜力在于它可能催生新的基于视觉传感器的侵入性更小的诊断和治疗，从而导致更小的疤痕，更小的风险，更少的痛苦，更少的不适，更少的麻醉需要，以及患者更短的恢复时间。由于规格的挑战性，该项目也对VLSI设计和无线通信技术产生了重大影响。低功率、低价格的一次性变送器将使内窥镜检查变得负担得起，并给患者更多自由。来自不同先进传感器的高质量高数据率视频将为医生提供更详细的医疗和诊断信息。如果这项技术开发成功，微型机器人可以成为一种方便可靠的工具，用于侵入性较小的诊断或手术。像这样的设备可以给患者带来更多的便利，让他们更愿意参加考试。

This Small Business Innovation Research (SBIR) Phase I project proposes to demonstrate the feasibility of an efficient high throughput video broadcast system over the Medical Implant Communication Service (MICS) band for camera pill and micro robot technologies while maintaining ultra low power consumption. Current camera pill designs have relatively low data rate and high power consumption. The proposed system is designed to significantly improve the specifications over the existing systems in use. The intellectual merit of the proposed research lies in the design of an integrated circuit for camera pill applications which combines advanced digital broadband technologies like orthogonal frequency division multiplexing (OFDM), low density parity check (LDPC) code, and diversity combining with the state of the art VLSI architecture designs. Major expected advantages of this technology include: ultra high throughput, super low power and compact transmitter, low cost transmitter, long distance spec, real-time transmission, accurate synchronization algorithms, frequency bandwidth efficiency, and interference avoidance. Furthermore, if this high throughput system is used with other low rate devices, the remaining throughput can be turned into additional power saving automatically.The broader impact/commercial potential of this project lies in its potential of spawning new less invasive vision sensor based diagnosis and treatments which lead to smaller scar, less risk, less pain, less discomfort, less anesthesia need, and less recovery time for patients. Because of the challenging specs, the project also has significant impact on VLSI design and wireless communication technology. The low power and low price disposable transmitter will make endoscopy affordable and give patients more freedom. The high quality high data rate video from different advanced sensors will give doctors more detailed information in medical treatment and diagnosis. If this technology is successfully developed, micro-robots can become a convenient and reliable tool for less invasive diagnosis or surgery. A device like this can give patients more convenience and make them more willing to take an exam.
