Advanced modulation coding schemes for an optical transceiver systems–based OWC communication channel model

This paper examines advanced modulation coding schemes for an optical transceiver systems–based wireless communication (OWC) channel model. These techniquesinclude On-Off keying and return to zero (RZ)/non–return (NRZ) coding. The signal power level against time frequency spectral variations are measured. max.
