Abstract

A coset-based quantizer (CBQ) which quantizes the input sequence to {λn} ε ∈ (Λ/Λ′;C) is proposed in this paper. The class of coset codes C (Λ/Λ′;C) whose sublattice Λ′ is a scaled version of the cubic lattice is considered. In this case, the entropy of can be made as simple as that of k repetitions of a scalar entropy encoding. Some simulation results of CBQ for encoding the memoryless Gaussian source are presented.
