It contains some sysmobts specific ifdefs which enclose dead code. - Remove the sysmobts specif ifdefs and the dead code Change-Id: I33f3e0fd293ca8387fddf5ed20f642621e9680de http://cgit.osmocom.org/osmo-bts/commit/?id=1ef544ea246a73ef4404cb9622ca41fbe8e0b76b commit 1ef544ea246a73ef4404cb9622ca41fbe8e0b76b Author: Vadim Yanitskiy <axilirator at gmail.com> Date: Mon Mar 5 20:56:20 2018 +0700 common/l1sap.c: limit the minimal ToA for RACH bursts In general, RACH bursts should not arrive with negative offset. Let's limit early signal arrival up to 2 symbols, otherwise it is most likely noise, interference or a ghost.

There are also ghost RACH, interference and noise possible, so let's extend the filtering coverage.

So, if a RACH burst passed the BER check, but was dropped by ToA check, the counter of valid RACH requests could be increased anyway.

Let's fix this.
