Abstract :
Quantizer design algorithms for decentralized estimation are presented. Scalar quantizer design for the problem of multiple descriptions over a multiple-access channel is also studied. The importance of the initial index assignment is explained and an algorithm (based on simulated annealing) for choosing a good initial index assignment is derived
