After the IEEE 802.15.7-2018 A-QL color code for Optical Camera Communication, 2D-OFDM is one of the next generation for Mbps data rate transmission from a screen TX to a camera.
IMPORTANT: We now release new 2D-OFDM Codes (2D ACO-OFDM) and update existing Code adding many interesting features. Notably, TWO MORE new software packages are now included.
- Package 1: (ACO/DCO-OFDM Simulation) – NEW
- Package 2: (ACO/DCO-OFDM Optical Link) – NEW
- Package 3: Optimal DCO-OFDM Optical Link – Update
Please download the following PPT file for a review of the 2D-OFDM packages:
Technical features of the Packages
Here are some of advanced technical features from our 2D-OFDM code project that you may get beneficial from:
TX technical features:
- Read a file to transmit; Two-layer FEC code; Editable n-QAM modulation
- Change between ACO-OFDM and DCO-OFDM, and clipping factor for PAPR
- Editable MIMO (to change the number of independent sub-transmitter within a TX)
- Editable spatial cyclic-prefix; editable bolder-size to protect TX
- Controllable TX display size as each of tiny cells are re-sizable.
RX technical features:
- Multi-tasking and pipeline techniques for real-time image processing
- Auto-detection and tracking the transmitter
- Re-configurable TX extraction process
- Auto-threshold for preamble detection
- Re-configurable demodulation process
- Real-time data display and BER monitoring
- Real-time monitor Constellation diagrams
