Fixed-rate successively refinable scalar quantizers

The problem of successively refinable scaler quantizer design is considered. The weighted average of the expected distortion at each level of refinement is used as a quantizer figure of merit. Quantizers designed using this criterion can find application in many practical situations. Algorithms are presented for the design of both uniform and non-uniform quantizers and performance of quantizers designed for several sources using these algorithms is presented and compared with the performance of other scalar quantizers
