Abstract

MÉTODO PARA RECEBIMENTO DE UMA COMUNICAÇÃO VIA RÁDIO QUE SOFRE UM BLOQUEIO PERIÓDICO, RECEPTOR PARA RECEBER UMA COMUNICAÇÃO VIA RÁDIO QUE SOFRE UM BLOQUEIO PERIÓDICO, MÉTODO PARA TRANSMISSÃO ADAPTATIVA DE RAJADA DUPLA E MÉTODO PARA TRANSMISSÃO DE UMA COMUNICAÇÃO VIA RÁDIO QUE SOFRE UM BLOQUEIO PERIÓDICO. Revelam-se um receptor e um método para recebimento uma comunicação via rádio. O método inclui o recebimento de uma rajada codificada com um esquema de codificação de modulação (MCS) robusto como sinais RX; geração, para cada um dos sinais RX, de uma SNR de rajada, símbolos de decisão suave e um pacote; pesagem de cada um dos símbolos de decisão suave com uma respectiva SNR de rajada para calcular os símbolos suaves combinados usados para gerar um pacote de combinação de razão máxima (MRC); e seleção, a partir dos pacotes e do pacote MRC, de um pacote passado em CRC como uma saída. Revela-se um transmissor adaptativo de rajada dupla.
