In the Software Radio context, this paper capitalizes on the Common Operator technique to propose a reconfigurable architecture for the FFT and Viterbi algorithms. In the present work, the FFT and Viterbi structural similarities are investigated to build a common architecture around the two algorithms. FPGA implementation and experimental results are discussed in this paper.
