Abstract
We present here design techniques for trellis-coded vector quantizers with symmetric codebooks that facilitate low-complexity quantization a s well as partitioning into equiprobable sets for trellis coding, The quantization performance of this coder on the independently identicall y distributed (i.i.d.) Laplacian source matches the performance of tre llis-based scalar-vector quantization (TB-SVQ) [1], but requires less computational complexity.
