Arrangement for cancelling intersymbol interference and noise. |
摘要 |
<p>An arrangement for combating intersymbol interference and noise, which are introduced into a data signal (ak) transmitted at a symbol rate 1/T by a dispersive transmission channel (CH), comprises an adaptive equalizer (EQ) with a symbol detector (ID) for forming tentative symbol decisions (âk) as well as a post-detector (PD) for forming final symbol decisions (âk-M) using an auxiliary signal which is derived from the transmitted data signal (rk) at the input of the arrangement. By using a priori knowledge of the main character of the transfer characteristic of the transmission channel (CH) and by using as an auxiliary signal for the post-detector (PD) the input signal ( @k) of the symbol detector (ID) in lieu of the transmitted data signal (rk), this post-detector (PD) can be arranged in a non-adaptive and thus simpler way without a resulting noticeable loss of transmission quality.</p> |
