Paper abstract
-----
In this paper we discuss the performance of several enumeration techniques for lattice quantizers when the transmission channel is noisy. We consider the multiple scale leader lattice quantization structure and we test three variants of lattice vectors indexing for LSF parameters quantization. We compare the results obtained with the proposed methods and also compare with the results obtained with the codec G.729, in the presence of noise.
