Previously didn't actually check for positive or negative acquisition
until the call to general_work *after* the one in which the detection
statistics were generated
Using C++ 11 threading routines to create a worker thread that can
perform the FFT for acquisition in a non-blocking manner. By default
'blocking' is set to true, which is identical to the previous behaviour
(with the added overhead of an extra thread). When 'blocking' is set to
false, then the main thread does not wait for the worker, thereby
letting the receiver continue even when the FFT thread is working. This
is very useful for using FFT acquisition at higher sampling rates, where
the FFT cannot be performed in real-time.
The aim is to replace the separate pcps_multithread_acquisition_cc.
TODO: implement the same thing for the pcps_acquisition_sc
Adds code to solve the shared frequency channels for GLONASS satellites
during acq and trk, it is now decode responsability to fix the identifier
when decoding of ephemeris happens. It also adds more details in tracking
plotting and fixes silly bug that created false alarm.
The code fixes the computation of the carrier frequency for pcps
acquisition of GLONASS satellites by making it relative to the IF. Also
new plotting features are added to visualize results
Starts merging process of the acquisition and tracking code for GLONASS
processing developed by Gabriel Araujo. Fixes compile warnings and
errors introduced during rebase operation
Rather than changing the index type to uint16_t, I think it would be
better to use the volk_32f_index_max32* functions instead of the 16 bit
counterparts. This ensures backwards compatibility (the index was
previously 32 bit, even if the function name indicated that it was 16
bit) and also, for FFT acquisition we may encounter large FFTs with more
than 65 535 points
instead of volk_malloc, volk_free (which are missing from the volk
version distributed by ubuntu 14.04). Fix the include guard in
volk_gnsssdr_malloc.h
Thanks to @hoernchen
Change the initialization of max_dwells in pcps acquisition adpaters
due its value is forced to be 1 in gr_block constructor if boolean
"bit_transition_flag" is set to TRUE
