c3d52ff86e Merges #34 Major redesign of Tuner, Channel and Alias management.
Changes to model, view and controller components and updates all gui
editors.  Removes the configuration panel and tree and replaces with 3
new panels.  Updates playlist.xml to a new playlist_v2.xml format.

f4d8ea281d Initial commit of redesigned internal processing and audio management.
Note: Several of the decoders are currently non-functioning in this
commit.  If you want the latest functioning codebase, please checkout
the commit prior to this one.  All decoders will eventually be updated
with this new architecture.

Currently broken:
- Logging and recording
- Aux decoders (Fleetsync/MDC/LoJack/Tait)
- LTR/Passport decoders

Changes in this commit:
- Module architecture for decoders and components with central
provisioning by the DecoderFactory
- Transition from Complex sample stream processing to float buffer
processing for improved memory management
- Redesigned filter structures - to support buffers and streams
- Resolved several memory leak issues
- Universal sharing of the thread pool manager
- Added centralized audio management with call/user prioritization and
new gui with mute/volume controls
- Embedded audio metadata for eventual streaming support
- Redesigned ProcessingChain to support independent re-use
- Added new TrafficChannelManager to handle traffic channel allocations
- Traffic Channel pool size and Call timeout available in P25 and
MPT1327 configs
- Redesigned channel and decoder gui components

31482a1014 P25 Decoder - improved LSM decoding and IMBE audio decoding. Includes redesigned audio output class to handle automatic start/stop of audio playback based on availability of audio data. 2015-06-08 01:05:19 +00:00

bc5080aa4a P25 - updated automatic and direct frequency control to cleanup the code and allow P25 to better track frequency and PPM changes in the tuner and provide a cleaner implementation of the AFC component in the processing chain of all of the other decoders.
Changed C4FM symbol filter to reset frequency tracking values when the tuner's frequency or PPM values change.

Moved all frequency control pieces into the source.tuner.frequency package.

2c4b3ab1b5 P25 - enhancement for LSM demod phase lock errors - adds new sync pattern detectors to detect Costas Loop phase lock errors and apply immediate correction to enable accurate symbol slicing. 2015-04-26 16:58:25 +00:00

c12123a81b P25 - work in progress to improve CQPSK LSM audio output. Audio output is still choppy but greatly improved over the previous test release. 2015-04-25 23:21:20 +00:00

52f2e3bdca P25 audio work in progress - started work on exposing 88-bit (11-byte) IMBE voice frames from LDU messages. Added deinterleave, derandomize and the Golay(23,12,7) error detection and correction to LDU voice messages. Hamming edac still remains to be implemented. Plan to create a separate project to produce an imbe FormatConversionProvider that will convert 88-bit imbe frames to PCM audio that is then in a standard format for audio playback, recording, or conversion to another format like shoutcast. 2015-03-01 15:40:25 +00:00

7d948c4af4 P25 LSM work in progress. CQPSK demodulator is working now, but there is a slight phase error in the constellation (it's rotated right by 5-10 degrees). I'm not sure if this is an error coming from the decoder, or if it's reflecting a phase imbalance from the source tuner i/q data. 2015-02-16 23:14:23 +00:00

a65e821e85 P25 LSM decoder work in progress. Adds a CQPSK decoder based on Max's (KA1RBI) scope.py and gardner loop.
The CQPSK decoder is starting to take shape, but needs more tweaking and testing.  It's not keeping a good lock on strong P25 signals.  I have to add some more features to the intrumentation package to allow me to visualize the internals of the CQPSK decoder so that I can get a better sense of what needs fine tuning.

The CQPSK decoder may work for anyone that wants to sync the repo and run the build script.
