Although resource-centered and capability-centered network manufacturing alliance has been paid attention at home and abroad, its success rate is low. Non-homogeneous, multi-stage and dynamic game theory is one kind of advanced research methods, but it never be used in studying coordination model to improve the success rate of network manufacturing alliance. On the basis of this dynamic and systematic...
The combined demodulating and decoding algorithm of the system of M-ary Differential Phase-Shift Keying (MDPSK) concatenated with Low-Density Parity Check Codes in AWGN channels is analyzed in this paper. Concentrating on the above algorithm, we propose a design method of optimal LDPC code based on Extrinsic Information Transfer Chart. Meanwhile, as an example, degree distribution of LDPC code at...
According to EN1434 (European Standard) and OIML R-75(International Organization of Legal Metrology), there are two methods in heat measurement, and they are all steady-state methods of test. The performances of these two methods are analyzed. A conclusion is improved that the two methods used in variable flow heating system results in appreciable errors. So some accurately measuring models should...
