The performance of a code under the maximum-likelihood (ML) decoder highly depends on the weight enumerating function (WEF). However, how to compute efficiently the WEF of a polar code or a ...

In the atmospheric layer above it, about 10 to 30 miles up, is the stratospheric polar vortex, where every winter a sunlight-starved Arctic spins up a mass of cold air that, ultimately, dissipates ...

This paper describes the advantages of N-polar GaN HEMT by comparing device characteristics with those of Ga-polar HEMT. The N-polar GaN HEMT epi-structure, which was designed for RF devices, was ...
