Timing jitter’s influence on the symbol error rate performance of the L-ary pulse position modulation free-space optical link in atmospheric turbulent channels with pointing errors
Abstract. An analytical approach is proposed to evaluate the impact of timing jitter on the error performance of the L-ary pulse position modulation (L-PPM) free-space optical (FSO) link, under theExpand
Free-Space Optical Communication Using Coherent Detection and Double Adaptive Detection Thresholds
In this paper, <sc>on</sc>–<sc>off</sc> Keying free-space optical (FSO) communication with coherent detection and double adaptive detection thresholds is proposed. The 3-bit encoding and doubleExpand
Performance improvement of coherent free-space optical communication with quadrature phase-shift keying modulation using digital phase estimation.
The performance of coherent free-space optical (CFSO) communication with phase modulation is limited by both phase fluctuations and intensity scintillations induced by atmospheric turbulence. ToExpand
Evaluation on the capacity and outage performance of the free space optical system impaired by timing jitters over an aggregate channel
This paper proposed an analytical approach to evaluate the timing jitter’s impairment to the ergodic capacity and outage performance of an on-off keying wireless optical link, where the compound channel consists of Gamma–Gamma turbulence and pointing errors. Expand
Performance analyses of subcarrier BPSK modulation over M turbulence channels with pointing errors
An aggregated channel model is achieved by fitting the Weibull distribution, which includes the effects of atmospheric attenuation, M distributed atmospheric turbulence and nonzero boresight pointingExpand

We propose a non-data-aided algorithm of the cycle slip self-correcting carrier phase estimation (CSSC-CPE) which mitigates the cycle slips caused by blind CPE in the coherent wireless optical communication (WOC) system. Expand
Packet loss recovery algorithm based on row-column coding and RS coding
This paper provides a kind of packet loss recovery algorithms that combines single parity check and RS coding, in which case coding is done not only to a single data block but also to different blocks. Expand
Measurement Approaches and Implementation of a Fading Characterization Tester for Evaluating Optical Turbulent Channels
We propose the algorithms for measuring the outage and synchronization performance, bit error rate (BER), throughput, and fading statistics of an optical link. Expand
A Modified Viterbi Equalization Algorithm for Mitigating Timing Errors in Optical Turbulence Channels
In high-speed optical wireless communication (OWC) systems, timing errors can blur the edges of the received symbols, defined by the deviation of a signal’s timing event from its intended occurrence.Expand
