Hexacode-based quantization of the Gaussian source at 1/2 bit per sample

We present the performance of several suboptimal algebraic quantizers in 24 dimensions. The Gaussian source is encoded at 1/2 bit per sample using the binary extended Golay code C/sub 24/ and the hexacode H/sub 6/. We also propose two new suboptimal decoding algorithms for the hexacode H/sub 6/.
