Low-power RF chipsets for wireless, embedded sensing Project

This project explores the application of new commercial RF chipsets and research devices being developed at the MIT Microelectronics Laboratory to short-range, moderate-to-high bit-rate, ultra low-power, minimally-complex, channel-shared wireless communication for ubiquitously-embedded smart sensor modules and lightweight, reconfigurable communication networks.

A software radio base stationhas been designed to coordinate these sensor modules. This basestation was specified to subsample, then digitize, at the first IF (intermediate frequency). This early digitization allows the basestation to have a flexible, reconfigurable architecture. Since most of the signal processing was to be done in the digital domain, the same basestation should work for different modulation schemes.

The results of this study can be found in Zoe Teegarden's M.Eng. Thesis:
