In this paper, we apply the right preconditioned generalized minimal residue (GMRES-RP) method for the analysis of electromagnetic scattering from 1-D ocean surfaces. We first verify that the GMRES-RP method has the desirable features of high accuracy, robustness, and efficiency, and, hence, is well suited to such analysis. We then carry out this analysis(More)
Compared with existing systems, fifth generation (5G) mobile systems are expected to support diverse services and massive connectivity. Thus, multiple access schemes play a critical role. Recently, a codebook-based non-orthogonal access mode called sparse code multiple access (SCMA) has been proved to enable massive connectivity by allowing SCMA layer(More)
The handset MIMO antenna is studied by using an in-house developed MIMO system, which can accommodate up to 8 antennas at both Tx and Rx sides. At first, a group of handsets with different number of antennas are designed and fabricated. The mutual coupling and efficiency of the antennas are measured. Then the handsets are inserted into the MIMO system, the(More)
With rapid development of satellite technology in monitoring the ocean, a good understanding of the physical processes involved in the electromagnetic ocean-surface interaction is required. The composite surface models are usually applied in the analysis of the interaction, hence a systematical check of their region of validity is desirable. Based on a(More)
