Abstract

<B>MéTODO E SISTEMA PARA COMPENSAçãO DE DISTORçãO DE CANAL USANDO INTERPOLAçãO POLINOMIAL DE LAGRANGE<D> Para transmissão de rádio móvel digital, é provido um método novo de medir e corrigir a distorção em um canal de transmissão. Símbolos piloto conhecidos são inseridos na seq³ência de dados. Em um receptor, distorção dos valores conhecidos dos símbolos piloto representa a distorção de canal. Interpolação de Lagrange dos valores recebidos dos símbolos piloto conhecidos é usada para estimar a distorção de canal dentro dos símbolos piloto.
