Resumo: Este artigo apresenta uma avalialção da influência do deslocamento de frequência de sinal OFDM/QPSK em canal com desvanecimento Rayleigh devido ao efeito Doppler. Curvas de desempenho do sistema foram obtidas por simulação e comparadas para diferentes frequências máximas de deslocamento Doppler.

Palavras-chave: OFDM, canal com desvanecimento Rayleigh, simulação, deslocamento Doppler
