7c1f5723e6 remove unneeded stores in NEON protokernels 2016-03-27 13:00:04 +02:00
Carles Fernandez
d113835073 adding new kernel: volk_gnsssdr_32fc_x2_rotator_dot_prod_32fc_xn 
Including generic, SSE3 (aligned and unaligned), AVX (aligned and
unaligned) and NEON protokernels.

751764343c adding AVX2 protokerns 
I haven't found a way to do the rotator part better than with SSE3. Only
the dot product takes real advantage of 256-bit registers. Even tough,
the gain with respect to SSE3 is about 12%.

Managing memory with volk_gnsssdr instead of malloc and free. This seems

architectures.

26b18c19ee Added a generic tracking_loop_filter class 
This implements a generic loop filter. Based on the analog PLL filters
from Kaplan and Hegarty, with a bilinear (Tustin's) transform from
s-plane to z-plane ( 1/s -> T/2 ( 1 + z^-1 )/( 1 - z^-1 ) )

Also added tests. Note the "truth" outputs
were derived from an Octave implementation of the loop filter and
Octave's builtin filter function

b95219dbc6 Added two Carrier_rotate correlator utilities 
1) Carrier_rotate_and_EPL_volk

This is a very efficient VOLK based carrier wipeoff and
Early/Prompt/Late correlation. The carrier wipe off is done using the
VOLK rotator functions, which means there is no need to generate a local
replica sinusoid.

2) Carrier_rotate_and_VEPL_Volk

This adds Very Early/Early/Prompt/Late/Very Late correlation with the
VOLK rotator implementation of carrier wipe-off

This is a generic gnuradio block for handling 2 bit samples packed into

samples within the byte, as well as big or little endian ordering of the
bytes within a short.

This is a utility function for a generic sample source which will be
able to handle all of these cases for both real and complex signals.
