A robust signal quantization system based on error correcting codes

摘要: In this paper we propose a robust representation of digital signal based on error correction codes. For each frame the (N successive samples) binary decomposition, as (successive power 2) weighted sum vectors, is first considered. Then, vector projected into set codewords corresponding block code. The codes are designed so that their powers increases inversely to weight vectors since with high less sensitive disturbance. (decoding) thus appears form quantization can provide an interesting protection against noise and/or channel distorsion. Some applications showing utility proposed given.
