Abstract: This application relates to the field of wireless communications technologies, and discloses an encoding method and apparatus, to improve accuracy of reliability calculation and ordering for polarized channels. The method includes: obtaining a first sequence used to encode K to-be-encoded bits, where the first sequence includes sequence numbers of N polarized channels, the first sequence is same as a second sequence or a subset of the second sequence, the second sequence comprises sequence numbers of Nmax polarized channels, and the second sequence is the sequence shown in Sequence Q11 or Table Q11, K is a positive integer, N is a positive integer power of 2, n is equal to or greater than 5, K?N, Nmax=1024; selecting sequence numbers of K polarized channels from the first sequence; and performing polar code encoding on K the to-be-encoded bits based on the selected sequence numbers of the K polarized channels.

Abstract: Methods and systems for predicting airport capacity impact using a probabilistic weather forecast are disclosed. A method includes: receiving, by a computing device, a probabilistic weather forecast including a plurality of weather scenarios; determining, by the computing device, an airport capacity prediction for each of the plurality of weather scenarios included in the probabilistic weather forecast; clustering, by the computing device, the airport capacity predictions; and generating, by the computing device, at least one aggregated airport capacity prediction using the clustered airport capacity predictions.
