About the performance of WCS #10

Closed ftianf closed 5 years ago

ftianf commented 5 years ago

Hi,

I noticed that in README.md of mynewt-timescale-lib, the performance of 1s CCP is ~500ps. Got a few questions regarding the performance of CCP/WCS

How is this measured? Is there a way to repeat the Benchmark test in one of the apps?
If we change the profile to <1s CCP superframe, will this improve the 500ps skew?
Is it possible to share the source codes of timescale-lib?

Regards Feng

Hi Feng, Have a look at the https://github.com/Decawave/mynewt-dw1000-apps/blob/bottleneck/apps/matlab/wcs_stats.m. This is a Matlab script that I use to study the WCS performance. In principle < 1s CCP should improve performance but we have not validated this. The timescale algorithm compensates for skew and drift (rate of change of skew). We are not planning on open sourcing the timescale-lib at this time.

Thanks for answering my question. It's clear now.
