Recursively indexed quantization of memoryless sources

A recursively indexed scalar quantizer that performs as well as high-dimensional vector quantizers for several important sources, without the attendant complexity, is presented. The recursively indexed quantizer provides a simple technique, both in terms of design and operation, for use with entropy coding. It also provides a simple quantization technique for use in noisy channel conditions where a variable length code would be inappropriate but performance greater than that provided by Lloyd-Max quantizers is desired
