Constant Weight Space-Time Codes for Dimmable MIMO-VLC Systems

Blog Article

Visible light communication(VLC), which combines communication and illumination, is regarded as a potential wireless communication.For illumination requirements of Braces VLC systems, dimming control is a significant function.Many schemes have been proposed for multi-input multi-output (MIMO) VLC systems or dimmable VLC systems, but few schemes combine the two.

The dimming control scheme that has been proposed for MIMO-VLC systems in the reference still has a probability for improvement in spectral efficiency and error performance.This paper proposes a dimming control scheme that utilizes the constant weight space-time codes (CWSTC) to improve spectral efficiency and error performance for MIMO-VLC systems.Simultaneously, we also present EFAMOL EVENING PRIMROSE OIL the codeword structure and a low implementation complexity detection algorithm for the scheme.

Finally, performance analysis and simulation results provide comparisons between the proposed scheme and other existing dimming control schemes.
