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
GNSS-SDR.internal_fs_sps
The old name was misleading, since the units are samples per second and
not Hertz.
Backward compatibility is kept, so this change does not break any
existing configuration.
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
Resolves: #24
Rename "shift_resolution_" variable in some Acquisition adapters to
"doppler_max_" according to its meaning and change "ifreq" to "if"
because the value was not properly read. Delete unused variables.
Resolves: #23
message system. Removing the deprecated channel internal queue and its
references. Some tests that are using the old channel queue are disabled
in this version
the post correlation noise floor. If enabled
(.Acquisition_1C.use_CFAR_algorithm=true) as an option in the
acquisition configuration, it allows setting more stable thresholds in
the presence of non-gaussian front-end noise (which is the usual
behavior of front-ends....)
