| 摘要 |
This invention relates to a wireless telecommunication system receiver, comprising a demodulator (220, 230) adapted to demodulate a signal received from a source via a transmission channel to provide an error correction code word in the form of flexible or hard values, a decoder (240) adapted to decode said code word, characterised in that it further comprises decision means (250) adapted to receive an estimation of the fading coefficients of said channel during the transmission of said code word as well as an estimation of the noise variance or the signal to noise ratio, to deduce therefrom an estimation of the relative instantaneous mutual information to said channel, and to decide whether or not to inhibit the decoding of the code word by the decoder, according to whether the binary rate of transmission of the source is respectively greater than or less than a characteristic threshold of said instantaneous mutual information.
