  <doc>This block serves as an interface to the underlying Python functions for channel construction.
  
  Current channel types are: BEC/AWGN
  Block size must be a power of 2!
  Info Bits must be 0 smaller K  smaller N
  Design SNR does affect the target transmission SNR and thus performance.
  The parameter mu is only relevant for AWGN channels. It is passed on to the corresponding Channel construction algorithm.</doc>
