Patent abstract
The present invention relates to a method of coding a signal, in particular an audio or speech signal, wherein a codebook comprising k code vectors is provided for vector quantization of a signal vector representing a set of signal values of said signal(s), and wherein an optimal code vector of said codebook is determined by performing a codebook search. Parallelism is employed to accelerate the coding procedure. In particular, the codebook search is highly parallelised.
