testing
 2017-05-17 17:33:15 +02:00

- Removed break in sliding_cross_correlate_upchirp due to inaccuracy in
noisy signals

sliding_cross_correlate_upchirp if correlation
    percentage drops
+
Added DBGR macros to measure exucution time of functions

 2017-04-26 13:56:45 +02:00
Wosser1sProductions d814ea01f3 Better Sliding Cross Correlation 
+ Re-added sliding cross correlation, but now starts from the
index found by the falling edge detector, which enables
very fast cross correlation and yields much more
accurate results
~ Changed index_correction correlation percentage threshold
from 0.8 to 0.9 for accuracy improvements
 2017-04-19 21:43:06 +02:00
Wosser1sProductions de82afa631 Default GRC threshold and freq_grad_idx improvement

further testing)
- Removed log files, and added results to wiki
+ Added threshold parameter to the lora_receiver block
+ Added failsafe to stop demodulation when noise was reached after data
(packet length in HDR was wrong)

Wosser1sProductions 5de5e8f1ca Additional improvement in synchronisation 
~ 'make test' now properly runs the data in qa_BasicTest_XML

success
