Atmospheric optical communication has been receiving considerable attention recently for use in high data rate wireless links (Juarez et al., 2006)-(Zhu & Kahn, 2002). Considering their narrow beamwidths and lack of licensing requirements as compared to microwave systems, atmospheric optical systems are appropriate candidates for secure, high data rate,(More)
Recently, a new and generalized statistical model, called M or Málaga distribution, was proposed to model the irradiance fluctuations of an unbounded optical wavefront (plane and spherical waves) propagating through a turbulent medium under all irradiance fluctuation conditions in homogeneous, isotropic turbulence. Málaga distribution was demonstrated to(More)
An effective procedure for generating m equal-power log-normal scintillation sequences with any desired cross-correlation coefficient is presented. The method is focused on a multichannel generalization of the autoregressive variate generation method in order to satisfy Taylor's hypothesis of frozen turbulence. Then the effect of the turbulent kinetic(More)
In free space optical (FSO) communication, atmospheric turbulence causes fluctuation in both intensity and phase of the received light signal what may seriously impair the link performance. Additionally, turbulent inhomogeneities may produce optical pulse spreading. In this paper, a simple rate adaptive transmission technique based on the use of variable(More)
In this paper, the simultaneous use of a simple rateadaptive transmission scheme, based on on-off keying (OOK) formats with memory, and a new self-orienting receiver, alternative to conventional angle diversity techniques, is proposed in order to mitigate the effect of large variations of the signal-to-noise ratio in indoor wireless infrared communications.(More)
General analytical expressions are derived for the average bit error rate of an intensity modulation and direct detection link using unbounded optical wavefront with on-off keying signalling technique propagating under all possible irradiance fluctuation conditions. These expressions include in a single equation the link performance of most of the proposed(More)
In this Letter, closed-form expressions of ergodic capacity, outage probability, and outage rate are derived for an atmospheric optical communication link using intensity modulation and direct detection with unbounded optical wavefront propagating through a homogeneous and isotropic turbulent medium. The optical scintillation of the received signal is(More)
Introduction: Wireless optical communications systems based on non-directed configurations [1], more suitable for indoor networking, can be affected by large dynamic variations of signal to noise ratio (SNR), leading to possible link failures. In this sense, rate-adaptive transmission schemes are preferred in order to make the communication suitable to the(More)
