This paper addresses the problem of increasing the robustness to bit errors for two description scalar quantizers. Our approach is to start with an m-diagonal index assignment and further apply a permutation to the indexes of each description to increase the minimum Hamming distance dmin of the set of valid index pairs. In particular, we show how to construct linear permutation pairs achieving dmin 3, and establish a lower bound in terms of the description rate R, for the highest value of m for… CONTINUE READING
