Abstract

DISPOSITIVO DE TRANSMISSãO DE RADIO, DISPOSITIVO DE RECEPçãO DE RáDIO, MéTODO DE TRANSMISSãO DE RáDIO E MéTODO DE RECEPçãO DE RáDIO. A presente invenção refere-se a um dispositivo de transmissão de rádio capaz de aperfeiçoar as características de taxa de erro de recepção de um receptor. Neste dispositivo, uma unidade FFT (Transformação Fourier Rápida) (102) sujeita um sinal de transmissão a uma operação FFT, na qual um sinal em um domínio de tempo é convertido para um sinal em um domínio de freqüência. A unidade de controle (103) controla a potência de transmissão do sinal de transmissão operado pela FFT no domínio de freqüência. Uma unidade IFFT (Transformação Fourier Rápida Inversa) (104) sujeita o sinal de transmissão possuindo sua potência de transmissão controlada, a uma operação IFFT, na qual uma conversão inversa é feita em um sinal no domínio de tempo. Uma unidade de transmissão RF (106) transmite o sinal de transmissão operado com a IFFT em uma portadora única.
