Investigation of rarely studied gravel layers found in the loess in Shandong Province, eastern China, reveals the fabric characteristics of two gravel layers (G1, G2) and the sedimentary characteristics of loess at the typical and well‐preserved Heiyu section (HY), where, to determine the paleoclimatic changes during Marine Isotope Stage 3a. Optically stimulated luminescence dates of the HY formation...
A modified blind MUD algorithm in the cooperation network is presented. By improving the subspace model and subspace tracking algorithm, it resolves the problem of fast matrix decomposition in the blind MUD algorithm. The paper analyzes convergence rate, anti-interference and algorithm complexity, and so on. The simulation results have been presented the modified algorithm can improve the convergence...
