Abstract :
A lattice vector quantization encoding method is developed based on ℓ1-norm-based enumeration and bit-plane coding. The algorithm is implemented for the cubic lattice, can handle arbitrary vector dimension, and is suitable for transform, subband, or wavelet coding applications. Moreover, the algorithm can possibly extend to other binary lattices.
