  • Process and device for decoding a radio frequency transmission channel, especially for a terrestrial digital broadcast using OFDM modulation
    Patent number: 6426981
    Abstract: The soft decisions associated with the quadrature digital signals received are calculated on the basis of at least one parametric law slaved to the minimum value of the rate of erroneous bits. The value is determined at the output of a Viterbi decoder in a microcontroller by varying the parameter of the law. The approach may be applied to applications including terrestrial digital broadcasting according to the DVB-T standard using OFDM modulation.
