A Flexible Multiband Reconfigurable Receiver for Wireless Endoscopic Capsule Streaming Video

Abstract

An on-the-fly reconfigurable wireless receiver was developed to demodulate high-speed, multi-band modulated signals in the sub-GHz band. The extreme flexibility is enabled by an FPGA as central processing core, reconfigurable at runtime with any demodulation core. The receiver front-end is entirely controllable from a software GUI. The software platform allows high-speed real time transfer of demodulated wireless endoscopic capsule image data from the FPGA through a USB interface IC, for further processing on a PC. A newly developed FSK demodulation core is used as case study for assessing the receiver’s quality. The extreme receiver flexibility allows for efficient practical design space exploration in research for the most optimal high-speed communication system for wireless endoscopic capsule links.status: publishe
