Version 0.35:
- Fast fixed point downsampling extended to CS8 datatype (signed bytes) and more sample rates (i.e. support for HackRF). We illustrate on an Ubuntu laptop with an IQ sampled file at a rate of 12.288 MHz in 8-bit signed integers. The results without fixed point downsampling:
AIS-catcher -r CS8 moscow-12.288M.raw -s 12288000 -b -v -q
...
[AIS engine v0.34]: 212 msgs at 16.8 msg/s
[AIS engine v0.34]: 6001.74 ms
Hence, AIS-catcher identifies 212 messages with a decoding time of 6 seconds. Using the -F switch reduces the computation time to 3.1 seconds without an impact to the number of found messages in this case:
AIS-catcher -r CS8 moscow-12.288M.raw -s 12288000 -b -v -q -F
...
[AIS engine v0.34]: 212 msgs at 31.2 msg/s
[AIS engine v0.34]: 3131.34 ms
- Fine tuning of EMA model, EMA model seems to perform now at least as good and is faster.
- Fix CMAKE file for hackrf support on Raspberry Pi
- Fix CMAKE file for issue with compilation including ZeroMQ support on MacOS.
- Exponential Moving Average (EMA) model is now defaullt (e.g.
-m 2 -go PS_EMA on) - SDRPlay RSP1 and SDRPlay RSPDX support (only DX tested on Antenna A)
