measurement: substitue missing measurements
At the moment the measurement calculation of osmo-bts works by
collecting the measurement reports the phy emits during a measurement
interval. Normally one would expect a well defind fixed number here, but
some phys will not emit a measurement report for lost blocks. Also
blocks and their reports may get lost because of cpu overload etc.
The computation that is executed at the end of the measurement interval
computes over all received measurement. This evenutally means that
missing measurements will not taken into account and the result will
look better than it is in reality.
To fix this, the interval must be of a defined size and in cases where
less measurements as expected were collected, the algorithm must assume
they have been received with a 100%BER and take that into account.
However, all RSSI and TA/TOA related computations should continue to
rely on actual measurement data.
- make sure the algorithm works over a fixed interval
- replace missing measurements with 100%BER
- fix and extend unit-tests
