d02698a6de Apparent bug where min/max aren't initialized from value inside the buffer bounds.
The fix is less than ideal, it assumes that an incoming buffer length is always >= 1.

85383e488b std::fma not necessary with proper compiler options.
std::fma isn't available on Ubuntu 15.04 arm-gcc, apparently. Hence my reviewing this code...

5dcca89172 FSKProcessor: remove separate channel filter.
RRC filter alone will do the trick!

fc037c739a Comment about correct MatchedFilter usage.
Because the filter expects a combined translate/rotate and low-pass filter in the taps, the taps must be a multiple of the translate sinusoid period.

9e694ce836 AIS decoding and really bad UI.
The decoder needs a serious refactoring/decoupling.
The UI just dumps bits of the received packets into a console window, whcih scrolls too quickly in an AIS-dense area with a good antenna.

a366b3ac4f CRC class.
Has some more efficient code, commented out because I was having trouble getting it to work. However, it may have been due to the particular data I was trying to decode and CRC-validate.
