Abstract

métodos, sistemas e dispositivos são descritos para comunicação sem fio em um dispositivo sem fio. um dispositivo sem fio pode selecionar de forma adaptativa uma matriz de verificação de paridade para aumentar a confiabilidade da transmissão do sinal, adaptando-se a diferentes estatísticas de canais e tipos de canais (por exemplo, canais de apagamento, canais com ruído gaussiano branco aditivo e canais com alfabetos discretos ou contínuos). por exemplo, os códigos de polarização (isto é, códigos baseados em fileiras de uma matriz de polarização) podem ser usados para construir matrizes de verificação de paridade on-the-fly, dada uma estimativa de condições de canal dinâmico ou estruturas de canais diversas. o canal pode ser decomposto em subcanais polarizados correspondentes aos códigos de polarização, e perfis de informação mútua podem ser determinados para cada um dos subcanais polarizados. a matriz de verificação de paridade correspondente aos códigos de polarização pode ser construída com base no perfil de informação mútua de todos os subcanais polarizados. o dispositivo sem fio pode codificar ou decodificar dados com base na matriz de verificação de paridade construída.
