% VitEnc			Viterbi Encoder function - performs Viterbi Encoder according to  
%					genration polynom 
% 
% 						Inputs: x - input data (binary form) 
%  							  G = [g1; g2; ...; gN] - matrix of generation polynomials 
%                         Walsh - Used row of Walsh matrix 
% 						Outputs: y - Viterbi Encoding sequence
