Performance of synchronous optical receivers using atmospheric compensation techniques.
We model the impact of atmospheric turbulence-induced phase and amplitude fluctuations on free-space optical links using synchronous detection. We derive exact expressions for the probability density function of the signal-to-noise ratio in the presence of turbulence. We consider the effects of log-normal amplitude fluctuations and Gaussian phase fluctuations, in addition to local oscillator sh...
متن کاملPerformance of Coherent Lidar Receivers Using Atmospheric Compensation Techniques
We present recent studies on the impact of phase and amplitude fluctuations on Doppler lidars using coherent detection. As there is an emphasis on elucidating those implications of the atmospheric propagation problem that bear on the design and reliability of optical coherent lidar systems, we consider in a unified framework the effects of atmospheric turbulence and diffuse target speckle on th...
متن کاملEffects of atmospheric compensation techniques on the performance of synchronous receivers
We present recent studies on the impact of atmospheric turbulence on free-space links using either synchronous or nonsynchronous detection. We compare options for atmospheric compensation, including phase compensation and diversity combining techniques. We consider the effects of log-normal amplitude fluctuations and Gaussian phase fluctuations, in addition to local oscillator shot noise, for b...
متن کاملCapacity of coherent free-space optical links using atmospheric compensation techniques.
We analyze the ergodic capacity and epsilon-outage capacity of coherent optical links through the turbulent atmosphere. We consider the effects of log-normal amplitude fluctuations and Gaussian phase fluctuations, in addition to local oscillator shot noise, for both passive receivers and those employing active modal compensation of wavefront phase distortion. We study the effect of various para...
متن کاملPhase Diversity Techniques for Coherent Optical Receivers
Abstruct-In the present state of the art, coherent optical receivers most often operate in the heterodyne mode. Here a photodiode-,amplifier combination having bandwidth greater than twice the bit rate ( B ) is needed: indeed bandwidths considerably greater than 2B are preferably employed to ease design of the bandpass filter needed for noise limitation, and to avoid demodulator penalties in so...
