The encrypted signal is then transformed by matlab DFT precoding matrix to lessen matlab programming PAPR of matlab programming OFDM signal. After that, matlab programming encrypted and DFT precoded OFDM are transmitted over matlab VLC channel. The simulation outcomes show that matlab programming proposed image safety transmission scheme cannot only protect matlab programming DFT precoded OFDM based VLC from eavesdroppers but additionally improve BER performance. In this paper, matlab class of discrete Radon transforms namely Finite Radon Transform FRAT was proposed as matlab modulation method in matlab programming recognition of Orthogonal Frequency Division Multiplexing OFDM. The proposed FRAT operates as matlab data mapper in matlab programming OFDM transceiver instead of matlab programming customary phase shift mapping and quadrature amplitude mapping that are frequently used with matlab programming regular OFDM according to Fast Fourier Transform FFT, by matlab programming way that ensure expanding matlab programming orthogonality of matlab programming system. The Fourier domain attitude was found here to be matlab programming more appropriate way for obtaining matlab programming ahead and inverse FRAT. The cost of matlab programming proposed system is largely reduced. In this paper, an adaptive orthogonal frequency division multiplexing OFDM modulation scheme with 128/64/32/16 quadrature amplitude modulation QAM and orthogonal circulant matrix transform OCT precoding is proposed and experimentally demonstrated for matlab visible laser light conversation VLLC system with matlab low-cost 450 nm blue light laser diode LD. The functionality of OCT precoding is compared with prevalent matlab programming adaptive Discrete Fourier Transform spread DFT spread OFDM scheme, 32 QAM OCT precoding OFDM scheme, 64 QAM OCT precoding OFDM scheme and adaptive OCT precoding OFDM scheme. The experimental results show that OCT precoding can achieve matlab fairly flat signal to noise ratio SNR curve, and it may give performance advantage in bit error rate BER. Furthermore, matlab programming BER of matlab programming proposed OFDM signal with matlab raw bit rate 5. 04 Gb/s after 5 m free space transmission is less than 20% of soppy decision forward error correlation SD FEC threshold of 2.
