A new video coding method is presented in this paper, which has been applied to the remote microscope monitoring system (RMMS). Using a criterion deduced from DCT (Discrete Cosine Transform) and quantization formulas and a criterion gotten by researching the characteristic of DCT coefficients distribution and experiment results, the method can detect(More)
Unipolar orthogonal frequency division multiplexing (U-OFDM) dimming control has been introduced for indoor visible light communication (VLC) systems, which demonstrates significant BER performance and power efficiency advantages over direct-current biased orthogonal frequency division multiplexing (DCO-OFDM) at the expense of half the spectral efficiency.(More)
