David Protzman 94297ff21c Added decode block 2022-09-22 21:15:13 -04:00
David Protzman 08cd68ab52 Added fft and filter libraries 2022-09-22 21:06:44 -04:00
David Protzman ce69f6fc3c Working on porting to 3.10 2022-09-22 21:03:39 -04:00
David Protzman 3bc45fe703 Added comments 2022-06-26 17:10:11 -04:00
David Protzman 39d419e318 No longer outputting NaN values for divide by zeros 2022-06-26 15:17:16 -04:00
David Protzman a4c21fdf91 Now using the volk inverse sqrt function 2022-06-26 15:16:49 -04:00
David Protzman df985ba877 Moved dot_prod to normalized_xcorr_estimate 
The dot_prod module ended up being a full on normalized cross correlation module, so it made sense to replace the old normalized xcorr module
 2022-06-26 10:24:05 -04:00
David Protzman 85f39daf0b Added complex noise function 2022-06-24 01:07:12 -04:00
David Protzman 4cb98e4429 Removed the epsilon add 
This was an attempt at getting the divide by zeros to stop, but if this didn't do it then it might be that the issue isn't a divide by zero.  Will need to create a MATLAB test to find out what's actually happening
 2022-06-24 01:06:49 -04:00
David Protzman 3335f6e3ea Working much faster now 
There are still some blanks in the o'scope plots which makes me think that there's either a divide by zero, or some gaps in the output values
 2022-06-24 01:04:40 -04:00
David Protzman 574f1aaccd Added dot product block 
It's working, but very slowly at the moment
 2022-06-24 00:21:36 -04:00
David Protzman 885262b97e Moved the plotting logic out of the main test 2022-06-23 22:18:00 -04:00
David Protzman 957ad6934d Added CMake config option for MATLAB install directory 2022-06-23 22:17:31 -04:00
David Protzman ba5b1a2593 Added variance block 2022-06-23 21:42:57 -04:00
David Protzman 675fc65dfc Added missing CMake file for the norm xcorr est block 2022-06-20 16:43:49 -04:00
David Protzman 1ba794cbee Converted normalized_xcorr to use VOLK malloc'd arrays 
This is to get better performance from the VOLK calls
 2022-06-20 16:43:32 -04:00
David Protzman c6598f9253 Added normalized xcorr estimate block 
This is just a wrapper around the normalized_xcorr class
 2022-06-20 16:42:47 -04:00
David Protzman 4b46d30248 Stripped down normalized cross correlator 
This new version is much more of an estimate of the cross correlation, but it's a *lot* faster.  Still need to do more real world testing of it
 2022-06-20 13:07:31 -04:00
David Protzman 2e33165cbe Turning on all available optimizations 
This is to help the correlation module run at line rate
 2022-06-20 13:06:08 -04:00
David Protzman 7606a61e8a Added runtime configurable threshold to extractor 2022-06-20 13:02:27 -04:00
David Protzman 66b749c3ad Added abs squared function 2022-06-20 12:49:02 -04:00
David Protzman 0fdac0e259 Fixed bug in running average tracking logic 2022-06-19 14:47:17 -04:00
David Protzman 10052a6b8d Converted to running average to get a small performance gain 2022-06-19 13:58:16 -04:00
David Protzman c89d6e6004 Normalization is working properly, but it's crazy slow 2022-06-19 13:42:58 -04:00
David Protzman 17f3465f3a Initial commit for normalized cross correlation function 
This is the crazy slow version!
 2022-06-11 12:56:32 -04:00
David Protzman bb791dbac5 Added functions for mean and var 2022-06-11 12:55:31 -04:00
David Protzman 5d59a14618 Updated drone_id_test GNU Radio example graph 
Increased number of extracted samples to help with processing in MATLAB
Changed default RX gain from .35 to .55
Disabled the offset block (not used for SDR based processing)
Removed the time sync block as it's no longer needed
 2022-06-09 00:32:34 -04:00
David Protzman 112454c3a8 Now saving off more vectors for debugging 2022-06-09 00:28:18 -04:00
David Protzman ad1ad97181 Fixed typo in received ZC sequence saving logic 2022-06-09 00:27:48 -04:00
David Protzman b915386ead Dropped threshold down to .2 2022-06-09 00:27:23 -04:00
David Protzman 769daa80cc Printing message if the total sample count isn't valid 
This should never happen, but for when it does...
 2022-06-09 00:27:13 -04:00
David Protzman beaeec30fc Fixed copy paste error in sample saving 2022-06-09 00:26:44 -04:00
David Protzman 3aa1b77e0b Now outputting each burst that comes into demodulation 
This used to happen in the time_sync block, but that block is no longer used
 2022-06-09 00:12:48 -04:00
David Protzman c863755ff8 Now writing out each received ZC sequence with a counter 2022-06-09 00:01:58 -04:00
David Protzman 7a3de6b0ce Increased number of samples extracted from the beginning of the burst 
This is to help MATLAB do demod since it needs a fair amount of padding before and after the burst
 2022-06-08 23:57:29 -04:00
David Protzman e36349b8a1 Now incrementing the file number for bursts coming into time sync 2022-06-08 23:56:48 -04:00
David Protzman 0729e4620e Moved the XOR_BIT_VEC to a constant static member variable 
This was being created for every burst which was just wasteful.  It was done that way because I was in a hurry =\
 2022-06-08 23:55:14 -04:00
David Protzman 4aa81eb2b9 Added CMake build dirs to ignore file 2022-06-08 23:53:35 -04:00
