摘要： A communication apparatus (120) comprises a redundancy encoder (200) for encoding an input information signal to obtain an encoded output sequence of information units, including information of the input signal and redundant information. Furthermore, the communication apparatus (120) comprises an encrypter (202) for encrypting the encoded output sequence to obtain an encrypted output sequence of information units, the encrypter (202) comprising a sequence manipulator (204) for manipulating the encoded output sequence which includes an interleaver (306) having an interleaving rule controllable with a secret encryption key, and a puncturer (308) for applying a puncturing pattern controllable with the secret encryption key, which is only known to an intended recipient of the input information signal.

摘要： An apparatus for providing a set of channel input symbols comprises a processing unit for encoding a plurality of information bit, the processing unit being operative for providing a set of processed values, means for providing channel capacity information indicating an achievable number of information bits per channel input symbol, and means for differently processing a number of successive sub-sets of processed values, wherein the number of successive sub-sets of processed values results in the number of processed values, to provide the set of channel input symbols using the channel capacity information, wherein the means for differently processing is operative to apply a different processing scheme to each sub-set of processed values, wherein the processing scheme for a sub-set of processed values is dependent on the channel capacity information. Therefore, an efficient exploitation of a communication bandwidth can be achieved.
