I am currently working on a project utilizing the nRF52840 DK and dongle to measure distances between devices. In the process, I am leveraging the nrf_dm application, which calculates MCPD distances using various methods such as high_precision, IFFT, phase_slope, RSSI_openspace, and best.
I would like to gain a deeper understanding of the algorithms behind these methods:
- How does each of these techniques contribute to distance estimation?
- What underlying signal processing techniques or mathematical models are applied in these methods?
- Where can I find the corresponding implementation (source code or documentation) within the
nrf_dmapplication's source files?
Any references to technical documentation, source code locations, or related research materials would be greatly appreciated.
