  • Methods in a communication system
    Publication number: 20010027536
    Abstract: The invention relates to a method for transmitting data frames and a matching method for receiving data frames. According to the method for transmitting data frames, when retransmissions are necessary, modified data frames (S502) produced by applying a bit pattern modifying function (F1) to the originally transmitted data frames (S501) are transmitted. According to the method for receiving data frames, when data frames (S503) fail a first cyclic redundancy check, a second cyclic redundancy check is performed on modified data frames (S504) produced by applying the inverse (F2) of the bit pattern modifying function (F1) to the data frames (S504).
