1. transmitter in mobile communication comprises:

  • First and second bit inserters are used for respectively known bits being inserted corresponding source user data bit flow on the precalculated position;

    First and second channel encoders, the bits of user data stream that is used to encode and is inserted with bit is to produce the user symbol after encoding respectively;

    First and second rate matchers are used for the user symbol rate is matched given channel user symbol rate respectively;

    The 3rd channel encoder is used for coding source control data bit stream, to produce the control character after encoding;

    The third speed adaptation is used for the control character rate is matched given channel control character rate;

    Multiplexer is used for the output of multiplexed first rate adaptation, the output of second rate matchers and the output of third speed adaptation;

    The channel speed adaptation, the symbol rate matched that is used for exporting from described multiplexer is to given channel symbol rate;

    AndChannel interleaver, being used for the channel is the interweave output symbol of described channel speed adaptation of unit.
