NLOS mitigation

Are there any suggestions for NLOS/multipath error mitigation in DW1000? The APS006 suggests methods for identification. it suggests rejection or weighted average for mitigation which would not be applicable in our scenario. We require a mechanism to compensate for the error once the timestamp is identified to be error prone.

You can’t compensate for the error unless you know how much it is.
You can only know how much the error is if you already know the distance.

If you have a known error source e.g. you know that in a certain region the direct path will be blocked from a certain anchor and the reflected path will bounce off a specific wall then you could potentially compensate for that. But this would be very installation specific and hard to apply to a general case.
