Abstract :
The authors propose to combat the effects of channel errors on vector-quantised data by optimising the energy allocation for the transmission of codeword symbols. In particular, they demonstrate that the application of transmission energy allocation to the natural binary code obtained from vector quantiser design by the splitting method outperforms established robust techniques such as index assignment, and explicit error control coding of most sensitive bits
