Abstract To address the problems of low efficiency, large error and high bit rate in phase unwrapping high-frequency fringes by traditional time-phase method, this paper we propose a coding method that quantizes multivariate gray code domain. Instead embedding stepped into sinusoidal pattern, embed pattern which reduces levels to larger extent widens longitudinal width between each step pattern. After camera captures deformed is dequantified difference level, high-quality ladder word...
To satisfy the performance requirement of LT codes with Unequal Erasure Protection (UEP) in underwater environment, Weighted Expanding Window Fountain (WEWF) code is proposed this paper. The WEWF can achieve strong UEP property by nonuniformly selecting input symbols within each window. overcome disadvantages terms redundancy lower prioritized segments, Correlation Chain Feedback (CCFB) also introduced to help transmitter precisely adjust encoding scheme. Asymptotic analysis and simulation...
Network coding (NC) is a promising approach to efficiently enhance the robustness and recovery capacity in Underwater acoustic sensor network (UWASN). However, undesired transmission redundancy additional resource limit further development for NC with applications UWASN. Based on analysis of intermediate nodes, new called encoding anticipation mechanism (EANC) proposed, by making nodes adjust adaptively operation on-off its capability (i.e. tradeoff between utility packet innovativeness...
