This means various types of database failure conditions (e.g. file existence, permissions, etc.) are not reported. This patch performs a small number of checks to make sure that the configuration is sane.

The difference is the midamble placements and lengths. Thus, there is no reason to have independent implementations. This patch creates a common call burstDetect(), while leaving the correlation window indexing in the original calls.

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.

Along the same lines, the tap values used during correlation are no longer stored in reverse, however, they are still assumed to be conjugated. Signed-off-by: Thomas Tsou <tom(a)tsou.cc> http://cgit.osmocom.org/osmo-trx/commit/?id=acc9ee9fc05914d40250e13ae885bf8… commit acc9ee9fc05914d40250e13ae885bf88bd9e672b Author: Thomas Tsou <tom(a)tsou.cc> Date: Tue Aug 20 19:31:14 2013 -0400 Transceiver52M: Replace convolve and related calls with SSE implementation This large patch replaced the convolve() call with an SSE vector enabled version. The lower C and SSE intrinsic based code operates on fixed and aligned vectors for the filter taps. The storage format of interleaved I/Q for both complex and real vectors is maintained. SSE filter tap values must: 1. Start 16-byte aligned 2. Number with a multiple of 4 between 4 and 20 for real taps 3. Number with a multiple of 4 for complex taps Non-compliant values will fall back to non-SSE usage. Fixed length iterators mean that head and tail cases may require reallocation of the input vector, which is automatically handled by the upper C++ interface. Other calls are affected by these changes and adjusted or rewritten accordingly. The underlying algorithms, however, are unchanged. generateGSMPulse() analyzeTrafficBurst() detectRACHBurst() Intel SSE configuration is automatically detected and configured at build time with Autoconf macros.

If we power on the transceiver, we will need the RACH sequence, so just allocate it during initialization.

The relevant information (time-of-arrival, channel gains, etc.) can and should be logged from transceiver instance itself.

Also remove the unnecessary pointer NULL checks prior to destruction.

The main transceiver object makes no use of the filter and there's no reason to pass it around. Initialize the pulse shape with the signal processing library, and maintain an internal static member like many of the other library variables. Similarly destroy the object when the library is closed.
