Ver1.0

low-speed VLC scheme

Ver1.1

Do some refractor stuff of the Ver1.0, more readable.

Ver2.1

1. Intergrated all encoding scheme and use OOK demodulation.

   • Spinalcode->Network coding->Manchester Encode->OOK

2. Some params:

   • Transmitter frequency: 5KHz
   • ADC sampling rate: 100KHz
   • SpinalCode: k=3,B=2,c=6
   • network coding:XOR

Interesting stuff

1. Decoding is much faster than ADC sampling.
2. Using ADC to demodulate OOK is not precise, therefore the next step is to use GPIO to demodulate.
