WiMAX as well as LTE prove to be state of the art technologies, with excellent performance but with certain advantages and disadvantages on both sides. The overall radio performance, however, is rather equal, thus clear-cut performance statements have to be based on higher layer design and even on network level.
—To assess the performance of future mobile network technologies, system level simulations are crucial. They serve to identify whether, and to which amount, predicted link level performance gains are obtained in an entire network. In this paper, we present a computationally efficient link-to-system level model for system-level evaluations of multiple-input… (More)
Silica (SiO2) is one of the most common materials on Earth. The crystalline form α-quartz is the stable silica polymorph at ambient conditions although metastable forms exist. α-quartz is a piezoelectric material, it can be produced artificially and is widely used for example in electronics and the biosciences. Despite the many application areas, the atomic… (More)
