Multiple-Input Multiple-Output (MIMO) Optical Wireless Communications

Abstract

Will-be-set-by-IN-TECH and receivers is transferred from an analogue to a digital domain by employing Fast Fourier Transform (FFT) and Inverse FFT (IFFT) blocks as demodulators and modulators, respectively.Therefore, all these aspects favour the implementation of OFDM systems in the current digital era.This chapter describes the characteristics of MIMO-OFDM systems applied to WOC, discussing their benefits, but also their drawbacks, as compared with other techniques used in order to obtain high-capacity optical data networks.
