[![Main Workflow](https://github.com/dernasherbrezon/jradio/actions/workflows/build.yml/badge.svg)](https://github.com/dernasherbrezon/jradio/actions/workflows/build.yml) [![Quality Gate Status](https://sonarcloud.io/api/project_badges/measure?project=ru.r2cloud%3Ajradio&metric=alert_status)](https://sonarcloud.io/dashboard?id=ru.r2cloud%3Ajradio)

## About

Software radio decoding written in Java. The idea of this project is to get blocks from the [gnuradio](https://github.com/gnuradio) and implement them in Java. This gives the following:

* No need for tooling. You could use [gnuradio-companion](https://wiki.gnuradio.org/index.php/HowToUse) to build a working pipeline, then use the same blocks to build the pipeline in Java.
  * All Java benefits: run same binaries on multiple platforms without compilation. Single programming language instead of Python and C++. Better tooling like IDE, profilers and memory analyzers.

## Demodulators

jradio supports high-level generic demodulators. They convert [I/Q signal](https://en.wikipedia.org/wiki/In-phase_and_quadrature_components) into the stream of [soft bits](https://dsp.stackexchange.com/a/27482) (0-255).

* [FSK](https://github.com/dernasherbrezon/jradio/blob/master/src/main/java/ru/r2cloud/jradio/demod/FskDemodulator.java)

 * [QPSK](https://github.com/dernasherbrezon/jradio/blob/master/src/main/java/ru/r2cloud/jradio/demod/QpskDemodulator.java)
 
## Modulators

Some generic modulators. They take hard bits and produce I/Q signal.

## De-framers

De-framer is a component that converts soft stream of bits into the frames of specific protocol.

## Auxiliary tools

Quite often decoding require some additional tooling. jradio has some.

### Forward error correction:

* [Viterbi](https://en.wikipedia.org/wiki/Viterbi_algorithm) [hard](https://github.com/dernasherbrezon/jradio/blob/master/src/main/java/ru/r2cloud/jradio/fec/Viterbi.java) and [soft](https://github.com/dernasherbrezon/jradio/blob/master/src/main/java/ru/r2cloud/jradio/fec/ViterbiSoft.java) decoders

### Randomization
 
 * [xoroshiro128+](https://github.com/dernasherbrezon/jradio/blob/master/src/main/java/ru/r2cloud/jradio/util/Xoroshiro128p.java)

 * [RayleighRandom](https://github.com/dernasherbrezon/jradio/blob/master/src/main/java/ru/r2cloud/jradio/util/RayleighRandom.java)
  
### CRC

Most likely the algorithm name can't say you much, so it is better to check [corresponding test case](https://github.com/dernasherbrezon/jradio/tree/master/src/test/java/ru/r2cloud/jradio/crc). Here is list of supported implementations:

* [CRC-8](https://github.com/dernasherbrezon/jradio/blob/master/src/main/java/ru/r2cloud/jradio/crc/Crc8.java)
 * [CRC-16/XMODEM & CRC-16/X-25](https://github.com/dernasherbrezon/jradio/blob/master/src/main/java/ru/r2cloud/jradio/crc/Crc16Ccitt.java)
 * [CRC-16/CCITT-FALSE/CRC-16-IBM](https://github.com/dernasherbrezon/jradio/blob/master/src/main/java/ru/r2cloud/jradio/crc/Crc16CcittFalse.java)
 * [CRC-16/ARC](https://github.com/dernasherbrezon/jradio/blob/master/src/main/java/ru/r2cloud/jradio/crc/Crc16Arc.java)
 * [CRC-16-NAIVE](https://github.com/dernasherbrezon/jradio/blob/master/src/main/java/ru/r2cloud/jradio/crc/Crc16SumOfBytes.java). Just sum of bytes.
 * [CRC-32C](https://github.com/dernasherbrezon/jradio/blob/master/src/main/java/ru/r2cloud/jradio/crc/Crc32c.java)

## Doppler correction

Doppler correction could be made using SigSource and Multiply blocks. Here is the sample code:

```java
PassPredictor predictor = new PassPredictor(tle, currentLocation);
SigSource source2 = new SigSource(Waveform.COMPLEX, sampleRate, new DopplerValueSource(sampleRate, satelliteFrequency, correctPeriodMillis, startTimeMillis) {

@Override
	public long getDopplerFrequency(long satelliteFrequency, long currentTimeMillis) {
		return predictor.getDownlinkFreq(satelliteFrequency, new Date(currentTimeMillis));
	}
}, 1.0f);
Multiply mul = new Multiply(source, source2, true);
```

Where "getDopplerFrequency" can be calculated using [orekit](https://www.orekit.org) or [predict4java](https://github.com/g4dpz/predict4java).

## Usage

Configure maven:

```xml
<dependency>
        <groupId>ru.r2cloud</groupId>
        <artifactId>jradio</artifactId>
        <version>1.57</version>
</dependency>
```
