Abstract

Codeword index assignment (CIA) is a key issue to vector quantization (VQ). The application of tabu search algorithm has made some achievement in solving the codeword index assignment. Combined with the notion of tabu search the energy allocation scheme has been also successfully used to overcome channel error sensitivity . In this paper, a new algorithm called modified tabu energy allocation algorithm (MTEAA) is applied to index transmission of codeword for the purpose ofminimizing the extra distortion due to bit errors. Simulated annealing (SA) technique and a new parameter are introduced in the iteration of the tabu energy allocation approach (TEAA) to improve the convergence performance. Experimental results demonstrate that the proposed algorithm is superior to TEAA and the conventional energy allocation algorithm (CEAA) by evaluating the performance of channel distortion.
