Three description lattice vector quantization for efficient data transmission

Lattice vector quantization is an ascendant technique that suits very well for multiple description coding (MDC) system. This paper introduces the lattice ℤ4 to be utilized for labeling function in the three description MDC system that consists of three encoders and seven decoders. Projection of a tesseract in three-space of lattice ℤ4 yields four outputs and the data are transmitted via three channels where one of the outputs is defined as time. Simulation results show that the three description quantization system is efficient that provides low distortion and good PSNR reconstruction quality.
