Capacity of wireless optical communications

IEEE Journal on Selected Areas in Communications, 2003
We consider the ergodic capacity and capacity-versus-outage probability of direct-detection optical communication through a turbulent atmosphere using multiple transmit and receive apertures. We assume shot-noise-limited operation in which detector outputs are doubly stochastic Poisson processes whose rates are proportional to the sum of the ...

Wireless optical communications: a survey

2004 IEEE Wireless Communications and Networking Conference (IEEE Cat. No.04TH8733), 2004
The demand for wireless broadband communications has been growing steadily for last several years. The congestion and the limitations on bandwidths of the radio spectrum have inhibited unrestricted growth of radio wireless systems. Wireless optical, however, holds the promise of delivering data rates that can meet the broadband requirements.
