Coherent Binary Polarization Shift Keying in Free Space Optical Turbulence Channel
نویسندگان
چکیده
In this paper the performance of a binary polarization shift keying (BPOLSK) modulated free space optical (FSO) link employing coherent detection in the presence of the atmospheric turbulence is investigated. First, a closed-form expression for the bit error rate (BER) of a BPOLSK-FSO system is presented taking into account the atmospheric turbulence-induced fading and noise. The BER performance of BPOLSK and on-off keying (OOK) with fixed and adaptive threshold schemes in the atmospheric turbulence channel is also shown.

BER Analysis of Coherent Free Space Optical Systems with BPSK over Gamma-Gamma Channels
We derived the average bit error rate (BER) of coherent free-space optical (FSO) systems with digital binary phase shift keying (BPSK) modulations over atmospheric turbulence channels with a gamma–gamma distribution. To obtain a generalized derivation in a closed-form expression, we used special integrals and transformations of the Meijer G function. Furthermore, we numerically analyzed and sim...
متن کاملEffect of Atmospheric Turbulence on AcquisitionTime of Ground to Deep Space Optical Communication System
The performance of ground to deep space optical communication systems is degraded by distortion of the beam as it propagates through the turbulent atmosphere. Turbulence causes fluctuations in the intensity of the received signal which ultimately affects the acquisition time required to acquire and locate the spaceborne target using narrow laser beam. In this paper, performance of free-space op...

In this paper a hybrid modulation scheme based on pulse position modulation (PPM) and binary phase shift keying subcarrier intensity modulation (BPSK-SIM) schemes for free-space optical communications is proposed. The analytical bit error rate (BER) performance is investigated in weak and saturated turbulence channels and results are verified with the simulation data. Results show that performa...

In this study, the authors theoretically study the performance of direct-detection free-space optical communication systems using binary phase-shift keying subcarrier-intensity modulation and avalanche photodiode (APD). The system biterror rate and channel capacity are theoretically derived in cases of log-normal and gamma-gamma channel models for weakto-moderate and moderate-to-strong atmosphe...
