function initPC(NKdesign_channelstringdesign_channelstatesilentflagfrozenbits) %Optional: N0 designSNRdB and silentflag (last three arguments)
%
% This prepares the collection of all implicit parameters related to
% polar coding & SC decoding; to be used by all subsequent routines later.
% (Including the memory resources to be used by the polar SC decoding)
%
% USAGE:
% initPC(NKdesign_channelstringdesign_statesilentflag)
%
% N - Blocklength; (*immediately adjusted to the least power-of-2 >=N*)
%
% K - Message length (Rate = K/N);
%
% design_channelstring - Must be one of (case insensitive)
% ‘AWGN‘ (default)
% or ‘BSC‘
% or ‘BEC‘
%
% design_channelstate - Channel‘s state to be assumed during the
% PCC algorithm. Usually as an initial. It must be one of:
% design-SNR (Default: 0dB; := Eb/N0 where (K*Eb/N) is the energy used during BPSK modulation of coded-bits)
% or design-p
% or design-eps
% *** Must match the ChannelString parameter (above) ***
%
% silentflag (optional) - Whether to print the last result or not
% ** defaults to 0 **
% (useful when automated for multiple runs in a Monte-Carlo simulation)
%
% frozenbits (optional) - User-defined (N-K)x1 frozenbits (ideally
% the FER/BER performance is identical for any choice
% but are critical to be known at receiver. May be used
% in cryptographical ideas for e.g.)
%
% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% Notes: 1. This routine/equivalent must be called (as many times
% if needed to adjust everything right) before we use
% any other utility around this package except the routines of the name “plotPCxxx()“
%
% 2. For AWGN channels we assume SNR=Eb/N0 defines the channel-state
% where (K*Eb/N) is the energy used by BPSK modulation of encoded-bits.
