51df92a05a Rename baseband_ais -> ais_baseband. 
So that ais_baseband and ais_application filenames can be sorted near each other.

26c23dc8a0 Use new FIR decimation in FSK demodulator.

424c0eac3f FIRAndDecimateBy2Complex: expose decimation_factor, bring work function into class. 2015-11-06 09:40:04 -08:00
Jared Boone
cde15e4271 Generalize fir_and_decimate_by_2_complex_fast. 
Permit decimation_factors other than 2.
Permit tap counts != 64 (but still must be multiple of 8).
Half the amount of tap memory required.
Performance is significantly degraded due to greater flexibility -- most likely due to separate sample buffer shift phase, instead of performing shift during output sample calculation.

Jared Boone
be78ed657f Remove taps_count template arg for FIRAndDecimateBy2Complex. 
Use heap to allocate samples and taps buffers, so filters of different lengths can be supported.

4aae77f565 MatchedFilter improvements 
Use single set of taps for positive and negative filters.
Reverse taps (since new samples are pushed into buffer from the high end).
Make complex multiply explicit to avoid fancy but irrelevant arithmetic checks.
Compute negative filter from conjugation of positive filter taps.
Move filter power and difference calculations into MatchedFilter.
 2015-11-06 09:40:03 -08:00

ab28639a3d Use std::move to move samples in buffer. 
Yes, std::rotate works, but it's fancy and does unnecessary work.

0bc8f551de Use matched filter for AIS GMSK demodulation demo. 
Less than optimal for plain FSK, but flexible enough to also support GFSK/GMSK. Not at all optimized for SIMD instructions, so may not perform adequately at Bluetooth/GSM rates.

4e0de9c4ad Fix clock configuration for M4. 
M0 launches baseband, so M4 clock can be set to PLL1. Provide a way to configure that per project, set to correct values for baseband project.

45d26abf10 Use correct memory region for persistent storage. 
Turns out 0x10088000 - 0x10089fff is not the right place. It's 0x40041000, and is only 256 bytes!
Move PPM to correct place, change representation to PPB for finer control.
Reset PPB value to initial value if read value out of bounds.
Clip PPB value on write to permitted bounds.
Contributes to resolution of issue #11.
