Essa t?cncia tem as vantagens de ser robusta contra incerteza de ru?do e ter baixa complexidade computacional. Nesta disserta??o foi proposta uma nova t?cnica de sensoriamento a partir de uma simples altera??o no m?todo originalCPSC.Resultadospreliminaresmostraramqueat?cnicamodi?cadaapresenta um melhor desempenho do que a original.
