Abstract

The present application concerns an encoding device comprising a FC 11 configured to generate m FC-output-bit-sequences by executing m polar encoding steps upon m FC-input-bit-sequences that comprise frozen and unfrozen bits, wherein m≥2. In an i-th polar encoding step of the m polar encoding steps at least one frozen bit is based on at least one unfrozen bit. The present application also concerns a decoding device comprising a processor configured to decode successively a polar-coded-bitstream comprising m-polar decoding steps, wherein m≥2. In an i-th polar decoding step of the m polar decoding steps at least one frozen bit is based on at least one unfrozen bit. Further, the present application concerns also correspondingly arranged encoding and decoding methods.
