Wosser1sProductions 30da0dedcd Merge deinterleave and comments 
- Removed break in sliding_cross_correlate_upchirp due to inaccuracy in
    noisy signals
~ Fixed upperbound in max_frequency_gradient_idx
~ Rewrote deinterleave function, now rotates bits to correct position
    instead of extensive masking
+ Added comment for every function (needs review)
~ Solved nibble reverse after Hamming decode by switching the order or
    ORing of the decoded data in Hamming itself
+ Added DBGR method to save timings to a file, a result for our setup
    can be found in examples/lora-timings
+ Added Python script to transmit and receive random data live for
    testing

sliding_cross_correlate_upchirp if correlation
    percentage drops
+

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

Wosser1sProductions de82afa631 Default GRC threshold and freq_grad_idx improvement 
+ Added threshold to GRC block ctor
+ Added default values for lora_receiver block

 2017-03-31 16:49:22 +02:00
Wosser1sProductions 296081ba39 Quick improvements 
+ Added generated whitining sequences (but not in actual code: needs
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 9f545e9f54 Test generation and whitening sequencing 
+ Added script lora_receive_all.py as a command line interface
    to set-up gnuradio on other platforms and receive LoRa packets
~ Automated whitening sequence generation with createWhiteningValues.py
    for various settings
~ Changed _examplify.py to also create XML database with the generated
    samples
+ Added same test sets, but for RTL-SDR and USRP (XML database)
