Generation of Screen-OFDM

In the previous post, an implementation demo of the Screen-OFDM system was shown. The detailed generation of Screen-OFDM (2-dimensional OFDM) is described in this post. Index Terms: Optical Camera Communication, OCC, OFDM, optical OFDM, 1D-OFDM, 2D-OFDM,  OFDM-OCC, Screen OFDM. Benefit of OFDM 1) General Benefits The concept of OFDM has reached sufficient maturity for standardization and employment …

What is Optical Region-of-Interest Signaling?

In the context of a safety assistance communication-based solution, OWC is a strong candidate for delivering the V2V communication power to cars. It is realized that the LED lighting is quipped to car mandatorily, meanwhile, a camera is considered as one of the indispensable sensors for car vision. The existence of supportive infrastructure enables the …
