Abstract:Different from the radio frequency bipolar complex signalling, LED-based visible light communication (LED-VLC) meets the non-negativity requirement by adding a bias component (BC) to a bipolar real-valued signal. Although many people know that there is a relationship between BC and LED characteristics, unfortunately, most of them chose to ignore it, and thus there has been little exploration of its impact on VLC.

Abstract This paper studies time-frequency connectedness among carbon assets, Bitcoin, and global stock markets by using the Diebold and Yilmaz method and the Baruník and Křehlík method, to investigate the hedging ability of carbon assets and Bitcoin in global stock markets. Our study finds that both carbon assets and Bitcoin play hedging roles in global stock markets.
