Physikalische Grundlagen der Radiologie,ectrum communication is fast acquisition of spread spectrum signal. For the lack of priori information, code phase and frequency offset are both random quantities, it usually takes a long time in signal acquisition, which would reduce the efficiency of the communication especially for the burst commVisual-Acuity 发表于 2025-3-25 08:40:45

Das Quantitative in der Radiologieepoch is used for initializing, and the wide-lane ambiguity is searched and fixed to calculate the basic ambiguity during this process. Then, the baseline solution is calculated by the least squares method, and gross error is processed by using robust estimation. Moreover, the residual error is consDissonance 发表于 2025-3-26 11:27:06

Pierre Bret,Christine Cuche,Gérard Schmutzearch of various abnormally detection methods, we could select the optimal method to process VTEC products, combined with earthquake cases of which the magnitude greater than Ms5.0 in global range from 2003 to the present. According to the principle of mathematical statistics, we found the relations提炼 发表于 2025-3-26 17:26:11
Pierre Bret,Christine Cuche,Gérard Schmutzng. Calculating all visible satellite not only makes the hardware design of the receiver harder, but also can’t guarantee to improve the accuracy of the positioning results, so it is significant to take a certain satellite selection algorithm to the visible satellites optimization. The traditional o
