This paper presents a QR decomposition core by exploiting Givens rotation for the generalized decision feedback equalizer (GDFE). A Givens rotation consists of phase extraction, sine/cosine generation and angle rotation parts. Combining the fixed-width modified-Booth multiplier and two-stage method (coarse and fine stage), we design an efficient QR decomposition core. By simulations, it is shown that the proposed QR decomposition core can be a feasible solution for GDFE.
