New Electronics and Communications Data Have Been Reported by Researchers at McMaster University (Constellation Collaborated OFDM for Visible Light Communication Systems)

By a News Reporter-Staff News Editor at Electronics Newsweekly -- Current study results on Electronics and Communications have been published. According to news reporting originating from Hamilton, Canada, by VerticalNews correspondents, research stated, "In visible light communication (VLC) systems based on LEDs, the limited modulation bandwidth of LEDs is a major challenge in achieving high-speed data transmission. To attain better performance on the low-pass frequency-selective fading channel, a constellation collaborated orthogonal frequency amplitude multiplexing (OFDM) is proposed in this letter."

Our news editors obtained a quote from the research from McMaster University, "In this novel OFDM, each two subcarrier frequencies are chosen as a pair. The symbols on the two subcarrier frequencies are respectively chosen from two uniquely factorable constellation pairs (UFCPs), with one random bit acting as a coordinator to control the two symbols."

According to the news editors, the research concluded: "Simulation comparisons demonstrate that the proposed constellation collaborative OFDM systems can attain 0.8-1.5 dB SNR gain over conventional OFDM systems."
