Abstract

"MéTODO PARA ESTIMAR A VELOCIDADE DE UM RáDIO MóVEL E RáDIO". Um sistema de estimação da velocidade de rádio móvel (100) inclui um bloco de autocorrelação (106) que determina a autocorrelação de um sinal recebido (104) utilizando um intervalo (102) . O bloco de determinação de energia (108) determina a energia do sinal recebido (104) e um bloco divisor (114) divide a autocorrelação (110) pela energia (112) . Utilizando uma tabela de pesquisa de função de Bessel (116) e a multiplicação pelo bloco <sym>/<sym> (118), uma estimativa (120) para a velocidade de rádio móvel pode ser calculada. Também é discutido um método para estimar a velocidade de um rádio móvel (500).
