better formating

getopt-fied and added stride
-
Richard Shaw committed [r4119]
Clean up how C flags are handled and set current minimum cmake to 3.0.
-
powf patch - thanks Danillo
-
Don Reid committed [r4117]
Revert a change I made which is also included in Danilo's changes.
-
Brad's patch for automatically sorted out USB devices that have changed order - thanks Brad
-
Initialize a variable to avoid warnings.
-
support for running ofdm_dev without CML, high doppler/hgh SNR option for phase estimation
-
run_single working again (uncoded)
-
Update 2 test scripts.
-
Old update to stm32 startup, to make use with gdb easier.
-
Update test to work after recent main code changes.
-
extra tofdm test for non-standard Nc
-
Refactored tval/nlower calculations due to STM32 issue.
-
Add a parameter to the verbose option, pass it along to ofdm.
-
accidentally setting up some LDPC constants when modem was meant to be operated uncoded. Thanks Don for finding this one
-
Steve Sampson committed [r4105]
Fix some of the ofdm_demod options
-
Add verbose level
-
support for efficient use of unused data bits, improved 2020 waveform performance by 1.7dB, examples in README_ofdm.txt
-
updated for latest incarnation of FreeDV 2020
-
building up support for unused data bits in LDPC codeword, all tests passing
-
first pass at (504,396) LDPC code support for FreeDV 2020
-
option for good use of unused data bits, when payload data is smaller than code
-
missing package, thanks Brad
-
fine patch from Danilo for a clever way to optimise memory on embedded devices by disbaling unused modes at compile time. Thanks Danilo
-
Add missing codec2_fifo.c
-
Add missing codec2_fifo.c
-
Update freedv files to use new codec2_fifo_* functions in codec2-dev.
-
Finish change from fifo_* to codec2_fifo_* functions, and
-
Check binary results. 700C matches exactly, 1600 has one byte that is different.
-
Add an option to return the count of differences instead of pass/fail
-
Simplify loop in dft()
-
first pass at high latitude ofdm waveform design
-
Allow test functions to have no arguments
-
refactored storage for Nc!=17 operation with no LPDC codec, arrays were being overwritten
-
moved verbose levels about to make output legible
-
Correct last update/left off size
-
Minor optimization in copying
-
Add to result text to say which set of tests report is for.
-
A simple script to run all of the current STM32 tests.
-
Remove temporary test directory
-
Delete a temporary test directory.
-
Fix a call to arm_cfft_f32 in codec2_fft.h
-
ofdm.c got left out of set_sync change
-
added feature to discard BER results from first few frames as these are often very high BER not representative of entire test
-
Change include for Sync on interldpc
-
Hide modem internals from API
-
Add a version of the Arm example, and another hacked to 512 inputs.
-
Simplify test by pulling code from other files into the main function.
-
Simplify be pulling code from other files into the test.
-
fifo rename to avoid namespace clash, thanks Danillo
-
Remove single-precision from octave
-
changed calculation of lowest carrier to use round() rather than floor() to avoid round off error between C and Octave, tofdm works on 22 carriers now
-
updated for latest LPCNet 1733 bit/s
-
Change Octave variables to single-precision
-
Cache init flags and output CMAKE_{C,ASM}_FLAGS during configuration.
-
leave ofdm test in a working state
-
modified tofdm.[mc] to work with variable Nc
-
Add gencodebooks cmake file for stm32.
-
Add patch for android and make codebook generation use cmake so it's more build system agnostic.
-
A standalone test for the codec2_fft_init issue in x86 and STM32 versions.
-
Add newer tests to the "all" target
-
Fix merger of last 2 changes.
-
Fix errors in STM32 test, update output of both to be more readable.
-
A version of the codec2_fft_init test for X86 to verify that it works correctly.
-
Convert DOS EOL to Unix
-
More align variables to unisgned char
-
Align variables to unsigned char
-
Save memory on static pilots
-
Add a simple test of some initialization. This could be extended in the future.
-
Move unalloc higher
-
Remove unused/empty header
-
Minor bug in debug output
-
Restore rand back, as it did change output
-
rand int64 to int16 for 32-bit compile, same output
-
Restore text message from integer (char) state variable.
-
Modify uw allocation for variable
-
After dinner code cleanup
-
New sync state mods
-
Add non testframes tests for api (to test codec use) , add codec only tests
-
UW symbol and bit mapping behaiving sensibly. We can change Nc and get good results. Made the call to fix UW and txt bits lengths, let payload symbols vary with Nc. Not sure if this is the best way to go, but it's a start!
-
working on user-defined modem config to match C code, works for 700D, but not general configs, am debugging ...
-
Update ofdm tests and Makefile to use new Math and sync_state.
-
Move constant computation out of function in ofdm.c
-
Minor style update
-
Minor style update
-
Comparison was flipped
-
Change states from strings to enum
-
patch from Danilo to clean up M4 and embedded support, thanks Danilo
-
More enabling if 700C mode for CORTEX_M4, this now works.
-
mbest optimisation for Codec 2 700C - thanks Danilo
-
ofdm.c memory reference vs stack
-
ofdm_demod minor update, add bool
