Quantizer design for distributed estimation with communication constraints and unknown observation statistics
Vasileios Megalooikonomou, Yaacov Yesha · IEEE Transactions on Communications · 2000
We consider the problem of quantizer design in a distributed estimation system with communication constraints in the case where only a training sequence is available. Our approach is based on a generalization of regression trees. The look-ahead method that we also propose improves significantly the performance. The final system performs similarly to the one that assumes known statistics.
