Compare 2D ACO-OFDM vs 2D DCO-OFDM

This post discovers the difference between 2D ACO-OFDM and 2D DCO-OFDM from implementation perspective. The Simulation Package allows us to test all the performance without any hardware configuration needed. Besides the simulation package (package 1), optical link package (package 2) and optimal optical link package (package 3) are within the 2D-OFDM Code packages. 2D Mapping … Continue reading Compare 2D ACO-OFDM vs 2D DCO-OFDM

NEW 2D-OFDM Codes available

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. NEW Package 1 (ACO/DCO-OFDM Simulation) New features This allows for choosing different modulation modes, including Modulation option: 2D ACO-OFDM or 2D DCO-OFDMChangeable clipping factor for reducing PAPREnable Inner-FEC and spatial-pilots … Continue reading NEW 2D-OFDM Codes available

Update OpenSource List

The OpticalPress Team is happy to provide Open Source Codes based on IEEE 802.15.7-2018 Optical Wireless Communication (OWC) standard, the most recent international standard that includes Optical Camera Communication (OCC) technologies. We believe that the codes are beneficial for the implementation of your novel ideas as well as practical comparison purposes. We were lucky and … Continue reading Update OpenSource List

(PPT) Presentation of technical features: A-QL vs 2D-OFDM

The following PPT file presents the technical features of A-QL code versus 2D-OFDM code. Also, we have included the performance comparison between the codes. Please download the file for more technical details. Presentation of technical features in 2D-OFDM and A-QL (PPT file)Download Notice: A-QL stands for Asynchronous Quick Link, a two-dimensional multi-band color code sequential transmission protocol from … Continue reading (PPT) Presentation of technical features: A-QL vs 2D-OFDM

(PPT) – BER measurement: 2D-OFDM vs A-QL

A-QL stands for Asynchronous Quick Link, a two-dimensional multi-band color code sequential transmission protocol from a screen to camera. The A-QL is one of mode within the IEEE 802.15.7-2018 Optical Wireless Communication standard. 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. … Continue reading (PPT) – BER measurement: 2D-OFDM vs A-QL

2D-OFDM for Optical Camera Communication

OFDM is well-known for LiFi; however, it is still fresh advanced waveform for OCC. This post shares an implementation of 2D-OFDM for Screen-to-Camera communication system in which a massive number of display cells brings a great advantage for communication. A full journal version of this topic is available online at IEEE Access here. System Architecture … Continue reading 2D-OFDM for Optical Camera Communication
