A Fully Implicit Domain Decomposition Algorithm for Shallow Water Equations on the Cubed-Sphere
Abstract. Popular approaches for solving the shallow water equations (SWE) for climate modeling are explicit and semi-implicit methods, both have certain constraints on the time st...

Three-Stage Serially Concatenated Codes and Iterative Center-Shifting K-Best Sphere Detection for SDM-OFDM: An EXIT Chart Aided
—Iterative K-best sphere detection (SD) and channel decoding is appealing, since it is capable of achieving a nearmaximum-a-posteriori (MAP) performance at a low complexity. Howe...
