Thanks u steve lord for u r reply, I am getting the error like orders must match while using deconv command for galois field data,when i run the following program,here my intention is i am looking to put the encoded message in systamatic form,can u please give some solution and please check is there any mistake with my vector representation for corresponding equations.
m=3; n=2^m1; k=4; % m=3; input=gf([1 1 0 1],m) /// input message x^3+x^2+1 a=gf(zeros(1,nk+1),m) a(1,1)=gf(1,m); A=gf(zeros(1,nk),m) A=a ///represents x^3 % b=gfconv(u,A) ///input*X^3
genpolyBCH = bchgenpoly(n,k) ///generator polynomial c=conv(input,A) ///input * x^3 [q,r]=deconv(c,genpolyBCH) ///(to do division input*x^3)/(generator poly)
Error using ==> gf.deconv at 16 Orders must match.
Error in ==> Untitled2 at 83 d=deconv(c,genpolyBCH) Thanking you,
