Abstract :
An iterative method for increasing the energy efficiencies of given Huffman sequences is introduced. The iteration scheme works by varying the roots and the radius of the Z-transformation of Huffman sequences. The algorithm allows the intensity of the variations of the possible root positions to be changed. In this way the energy efficiencies of long real and complex valued Huffman sequences can be optimized. The algorithm has been applied to known Huffman sequences. The resulting efficiencies of real and complex valued Huffman sequences are given up to 100 elements
