Transceiver52M: Disable energy detector
The adaptive energy threshold gating suffers a near-far problem
at certain gain levels. This is due to exponential threshold
raising, but linear decreases. A large signal level followed by
a period low signal level causes comparatively weak signals to
go undetected. Additionally, the algorithm performs differently
at multiple RF gain and/or input scaling levels.
This patch switches solely to correlation based gating for burst
detection. The main computational load with this approach is
sub-sample peak interpolation, which we disable during intial
detection.
