function pun_pattern = CreateWimaxPuncturingPattern( Nbits_pun, Nbits_unpun )
% CreateWimaxPuncturingPattern creates the puncturing pattern for use with the duobinary
% tailbiting turbo code (CTC) from the mobile WiMAX (IEEE 802.16e) standard.
%
% The calling syntax is:
%     pun_pattern = CreateWimaxPuncturingPattern( Nbits_pun, Nbits_unpun )
%
%     pun_pattern = the puncturing pattern (length Nbits_pun vector)
%
%     Nbits_pun = the number of bits after puncturing
%     Nbits_unpun = the number of bits prior to puncturing (not used)
