Channel estimation for asymmetrically clipped optical orthogonal frequency division multiplexing optical wireless communications

Abstract

A novel channel estimation method for asymmetrically clipped optical orthogonal frequency division multiplexingbased optical wireless communications systems is proposed. Different from the superimposed sequence used in traditional methods, the local matrix and superimposed periodic training are designed rationally. Furthermore, the channel impulse response… (More)
