Analytical Solution of Covariance Evolution for Regular LDPC Codes
Takayuki Nozaki, Kenta Kasai, Kohichi Sakaniwa
The covariance evolution is a system of differential equations with respect to the covariance of the number of edges connecting to the nodes of each residual degree. Solving the co…
Experimental Determination of the Gain Distribution of an Avalanche Photodiode at Low Gains
Kenji Tsujino, Makoto Akiba, Masahide Sasaki
A measurement system for determining the gain distributions of avalanche photodiodes (APDs) in a low gain range is presented. The system is based on an ultralow-noise charge--sensi…
Systematic characterization of upper critical fields for MgB thin films using the two-band superconducting theory
S. Noguchi, A. Kuribayashi, T. Ishida +9
We present experimental results of the upper critical fields of various MgB thin films prepared by the molecular beam epitaxy, multiple-targets sputtering, and co-…
Demonstration of near-Optimal Discrimination of Optical Coherent States
C. Wittmann, M. Takeoka, K. N. Cassemiro +3
The optimal discrimination of non-orthogonal quantum states with minimum error probability is a fundamental task in quantum measurement theory as well as an important primitive in…
Microstructure and kinematics of H2O masers in the massive star forming region IRAS 06061+2151
K. Motogi, Y. Watanabe, K. Sorai +14
We have made multi-epoch VLBI observations of H2O maser emission in the massive star forming region IRAS 06061+2151 with the Japanese VLBI network (JVN) from 2005 May to 2007 Octob…
On Field Size and Success Probability in Network Coding
Olav Geil, Ryutaroh Matsumoto, Casper Thomsen
Using tools from algebraic geometry and Groebner basis theory we solve two problems in network coding. First we present a method to determine the smallest field size for which line…
