cnv_encd.m

Viterbi Algorithm & Viterbi Decoder Matlab Code.(Provided both soft & hard decision ability). Note:

function output=cnv_encd(G,k,input)
%  		cnv_encd(G,k,input)
%  		determines the output sequence of a binary convolutional encoder
%  		G : the generator matrix of the convolutional code
%        	with n0 rows and l*k columns. Its rows are g1,g2,...,gn.
%  		k :  the number of bits entering the encoder at each clock cycle.
%  		input: The binary input seq.

%  check to see if extra zero padding is necessary
if rem(length(input),k) > 0    % input
