Abstract

DETECçãO EFICIENTE DE ERRO DE ACK COMO NACK. Um método e equipamento para determinar se uma transmissão foi recebida com sucesso em um sistema de comunicação de acesso múltiplo são reivindicados, Os primeiro e segundo pacotes de dados codificados são recebidos e decodificados. Os primeiro e segundo pacotes de dados são então recodificados, e correlacionados para determinar se os primeiro e segundo pacotes de dados recodificados são o mesmo. Se houver um grau de correlação elevado, um indicador de confirmação é transmitido para indicar que há um grau elevado de correlação entre os primeiro e segundo pacotes de dados recodificados. Se houver um baixo grau de correlação, uma determinação é feita de que o indicador de confirmação anteriormente transmitido foi corretamente recebido.
