MSc thesis project proposal

Phase domain ranging and localization for Bluetooth low energy or ZigBee

Project outside the university

IMEC/Holst Centre, Eindhoven
Ranging and localization is important in todays and future radio networks. Generally speaking, range information is obtained by measuring either time-of-flight (ToF) or received signal strength (RSS).  The highest accuracy is obtained with ToF, but this requires dedicated radios. RSS can be easily realized using popular communication radios, but is rather inaccurate.

In this project, a third option will be investigated based on multi-tone phase-measurements [1]. It promises a better accuracy than RSS and can be realized using radio front-end used by popular radios. Your task will be to investigate the application of compressive sensing on multi-tone phase-measurements for ranging and how it affects accuracy/performance.  Expected project duration is about 9 to 12 months. The assignment is done at TU Delft or at IMEC/Holst Centre, Eindhoven.
