This paper utilizes uniquely decodable codes (UDCs) in an M-to-1 free-space optical (FSO) system. Benefiting from UDCs' nonorthogonal nature, the sum throughput is improved. We first prove that property still holds, even fading channels. It further discovered receiver can extract each source's data superimposed symbols with only one processing unit. According to theoretical analysis and simulation results, gain up normalized UDC's rate high signal-to-noise ratio cases. An equivalent desktop...
Our previous work has proved that the uniquely decodable code (UDC) ability of enhancing throughput a free space optical communication (FSO) system. This paper quantitatively analyzes error performance and channel capacity UDC-FSO system under Malaga turbulence pointing errors. We first propose minimum distance superimposed patterns (MDSP) approximation to reveal universal symbol rate (SER) for systems. A closed form expression SER is further deduced special case 2 TXs. Based on SER, upper...
An analytical approach is proposed to evaluate the impact of timing jitter on error performance L-ary pulse position modulation (L-PPM) free-space optical (FSO) link, under gamma–gamma (ΓΓ) turbulence with pointing errors. The expression conditional symbol rate (SER) for a certain developed while Gaussian–Hermite polynomial approximation utilized derive closed-form average SER by jitter’s variance. It discovered that contributes an floor in both Monte–Carlo simulations and theoretical...
Deep space optical communication (DSOC) is becoming a hot topic. Pulse position modulation (PPM) an effective tool to realize DSOC benefiting from the feature of high sensitivity. In this paper, we analyze 2 × 1 PPM systems with photon-counting detectors, where distance difference between two links causes asynchronous superpositions at receiving end. Two synchronization algorithms are proposed estimate time offsets links, which optimal Global Maximum Likelihood Estimation (GMLE) and...
This paper proposed an analytical approach to evaluate the timing jitter’s impairment ergodic capacity and outage performance of on-off keying wireless optical link, where compound channel consists Gamma–Gamma turbulence pointing errors. Due complexity in deducing capacity, closed-form bounds are developed, as well asymptotic limit. Meanwhile, Gaussian–Hermite polynomial approximation is exploited obtain expression probability series. It has been verified by both theoretical results...
The divergence angle, as one of the important parameters terahertz radiation, is a significant indicator energy distribution beam and its accuracy affects signal-to-noise ratio system measurement. We focus on two 100 GHz continuous-wave sources with different angles propose method for analyzing contour envelope trend spot image using processing techniques, based intensity radiation. involves constructing conical surface point coordinates then iteratively obtaining propagation direction,...
The physical-layer network coding (PNC) becomes a popular research topic, and the multiuser PNC is still an open issue. This paper investigates uniquely-decodable codes (UDC) by using Iterative construction algorithm, applies generated UDC to that based on amplify-and- forward (AF) criterion. Due attractive features of UDC, sum data rate can increase with number users log-linearly. Moreover, only two time slots are needed for any user node obtain sequences transmitted arbitrary user, no...
