On index assignment and the design of multiple description quantizers
Pradeepa Yahampath · 2004
The practical design of multiple description quantizers for diversity-based communication is investigated. A simulated annealing based method is proposed for obtaining the optimal index assignment for a multiple-description vector quantizer. This method can be used to design quantizers having an arbitrary number of descriptions with equal or unequal transmission rates. According to the simulation results, the proposed method yields multiple-description quantizers with performance comparable with, or better than, previously reported results.
