An Implementation of MIMO and OFDM Based Visible Light Communication System for Indoor Environment

MIMO systems that use multiple LED light sources and photo detectors are attractive for visible communication lights proportion to their acquired capacitive and the number of parallel single input single output channel. The MIMO VLC system overcomes the capacity limitations caused by the limited LED modulate bandwidth by using the high SNR of the SISO channel provided according to general lighting requirements. This paper compares Enhanced Optical OFDM (EOOFDM), that's uses as an excessive-bandwidth performance approach, with 3 famous OFDM (Orthogonal Frequency Division Multiplexing) methods. The proposed mechanism would increase the information switch price through 1/8 instances as compared to different traditional structures, while preserving the identical information level with the ideal approach, the simulation outcomes display that the Eb/No of the proposed machine has expanded through as a minimum 0.65dB. With the ensuing outcomes, EO-OFDM can offer better information cost while OFDM above the channels with confined frequency bands. The simulation outcomes display that this approach can extensively minimize PAPR. At the same time, beneath the LED's non-linear restriction and confined aggressive range, the general achievement of this results is higher above the different competing solutions
