Data-Driven Symbol Defi nition for Color Shift Keying in Screen Camera Communications
(Universidad Nacional Tecnológica de Lima Sur, 2021)
Aiming to increase the data rate in screen camera communications, we intend to define symbols to be used in an M-ary color shift keying modulation scheme. With regard to the R, G, B format of a JPEG image, we generate ...
Mathematical expression of the bit error ratio in terms of the SNR and laser linewidths in digital coherent optical communication systems
(2021-01-01)
The development of high speed digital signal processors has enabled the migration from previous direct detection systems to digital coherent optical communication systems. The adoption of this technology in optical ...
