abstract = { In this paper, we have proved that the lower bound of the number of real multiplications for computing a length $2^{t}$ real GFT(a,b) $(a=\pm 1/2,b=0\ or\ b=\pm 1/2,a=0)$ is $2^{t+1}-2t-2$ and that for computing a length $2^{t}$ real GFT(a,b)$(a=\pm 1/2, b=\pm 1/2)$ is $2^{t+1}-2$. Practical algorithms which meet the lower bounds of multiplications are given. },
