Abstract

"CORREçãO DE DESVIO DE AMOSTRAGEM EM UM SISTEMA DE MULTIPLEXAçãO DE DIVISãO DE FREQuêNCIA ORTOGONAL" Um receptor de Multiplexação de Divisão de Freq³ência Ortogonal (OFDM) detecta e corrige desvios de amostragem no domínio de tempo. O receptor de OFDM amostra em sobreposição (62) uma seq³ência ou símbolo de treinamento em um sinal de OFDM recebido, correlaciona (64) a seq³ência de treinamento amostrada em sobreposição a uma cópia armazenada
