Abstract

Способ повторной передачи на основе автоматического запроса повторной передачи в системе связи, в котором пакеты данных, содержащие модуляционные символы, повторно передают на основании автоматического запроса повторной передачи и впоследствии объединяют с ранее принятыми пакетами данных, причем символы упомянутых пакетов данных модулируют с помощью блока отображения, использующего предварительно определенную совокупность сигналов. Повторно переданные пакеты данных повторно передают в форме версии избыточности, выбранной из множества различных версий избыточности. Согласно изобретению биты, подлежащие передаче, переупорядочивают до модулирования по всем повторным передачам в соответствии с выбранной версией избыточности.Международная заявка была опубликована вместе с отчетом о международном поиске.
