An Optical Array Receiver for Deep-Space Communication through Atmospheric Turbulence
The theoretical foundations of an optical array receiver consisting of relatively small telescopes are developed and analyzed. It is shown that optical array receivers can be designed to perform as well as a large single-aperture receiver on the ground, while enjoying significant advantages in terms of operational reliability, ease of future expansion to achieve greater capacity, and further ad...
متن کاملOptical Receiver for Coherently Detected Pulse-Position Modulated Signals in the Presence of Atmospheric Turbulence
Performance analysis and experimental verification of a coherent free-space optical communications receiver in the presence of simulated atmospheric turbulence is presented. Bit-error rate (BER) performance of ideal coherent detection is analyzed in Section II, and the laboratory equipment and experimental setup used to carry out these experiments are described. The key components include two l...
متن کاملDetection Statistics Of Multiple-Pulse Optical Signals Through Atmospheric Turbulence
Advisor Date Acknowledgments I would like to thank my parents who made it possible for me to begin my education in electrical engineering and for the love and support that they provided along the way. Similarly, I would like to thank my girlfriend who provided me with love and support as I pursued my Ph.D. She gave me much needed emotional support when times were tough, especially before my fir...
متن کاملAtmospheric-turbulence-induced power-fade statistics for a multiaperture optical receiver.
To estimate the probability distributions of power fades, we consider two basic types of disturbance in electromagnetic wave propagation through atmospheric turbulence: wave-front intensity fluctuations and wave-front distortion. We assess the reduction in the cumulative probability of losses caused by these two effects through spatial diversity by using a multiaperture receiver configuration. ...
متن کاملOptical wireless communications utilizing a dicode PPM PIN-BJT receiver
Original results are presented for an optical wireless system employing dicode pulse position modulation (DiPPM) and a PINBJT receiver. When operating at 0.85 m and a bit rate of 10 Mb/s, a sensitivity of 51 dBm (Pe 10 ) is achieved, which represents a 10.3-dB improvement, as compared to an equivalent PCM system. The work also demonstrates that DiPPM achieves comparable sensitivities to those o...
