Student project at imec (Thesis)
What will you be doing?
The range between two BLE devices can be estimated based on three different methods: (i) Received signal strength indicator (ii) Time-of-arrival or Time-difference-of-arrival, (iii) phase evaluation of the tone exchange between two radios. The phase-based ranging in combination with super resolution algorithms is more promising than other techniques in multi-path environments. The challenge in phase-based ranging is to estimate the channel response from the IQ samples on few tones and then estimate the distance from the channel response.
In this project, you will attempt to use the neural networks to estimate the channel response from the IQ samples at both devices which perform ranging. The recurrent neural networks can be evaluated as a starting point as there is temporal structure in the channel response of different tones. The estimated channel response will be then used in combination with super resolution algorithms and/or other neural network architectures to ultimately estimate the range between two devices. Depending on the performance and quality of the researched solutions, a publication in a reputed conference or journal is possible.
Literature survey on different architectures of neural networks used for the ranging application.
Identify promising architectures to estimate the channel response using phase measurement of two devices with reasonable complexity.
Model the system in MATLAB or Python.
Verify the ranging performance with some measurements.
