Abstract
rastreamento de fase de sequência única durante estimativa de canal em um sistema de comunicação mimo sem fio com taxa de transferência muito alta. em um sistema de múltiplas entradas e múltiplas saídas, a função de demodulação de cadeia de recepção de nó sem fio é melhorada para incluir o rastreamento de fase. ao invés da realização do rastreamento de fase durante os símbolos de dados que são trabalhosos para redes sem fio com taxa de transferência muito alta, os campos de sequenciamento longo (ltfs) vht embutidos no preâmbulo de um quadro são utilizados para o rastreamento de fase. tons piloto de fluxo único são adicionados durante a transmissão de vht-ltes. isso é explorado no lado de recepção para poder estimar o canal utilizando os tons piloto no primeiro conjunto de campos de sequenciamento longo. o segundo conjunto de campos de sequenciamento longo são então utilizados para estimar a fase dos tons piloto utilizando o canal estimado. a estimativa de fase assim obtida é aplicada continuamen te para outros ntons de dados recebidos por todo o vht-ltf dos símbolos de dados. os erros de fase decorrentes da falta de combinação pll e ruídos de fase são reduzidos na recepção, resultando em uma melhor razão sinal-ruído para diferentes níveis de variação de partes por milhão e desvio em frequência. adicionalmente, a estimativa de canal mimo é mais precisa, o que aperfeiçoa a rede sem fio como um todo quando esses dados de estimativa de canal mimo precisos participam na calibragem e estabelecimento de comunicação entre os nós sem fio.
