Abstract
A basic cell type full search vector quantization coder has a plurality of basic cells and a minimum distortion output vector detector. In each basic cell a common K-dimensional input vector is divided by b into b sub-blocks and n output vectors are read one by one out of a set of N output vectors. The output vectors are also divided by b. Comparison is made K/b times between the components of the input and the output vectors to detect one of n output vectors positioned at the shortest distance from the input vector. The detctor compares the outputs supplied by the basic cells and detects one of the output vectors producing the minimum distortion, whose index signal being an output of the coder.
