| 摘要 |
The present invention relates to a signal processing unit (120) for pre-processing signals for crosstalk mitigation. In accordance with an embodiment of the invention, the signal processing unit comprises a modulo unit (121) configured to determine individual modulo shifts (”) for respective transmit samples (U) to be transmitted over respective communication channels (H) based on first channel coupling information (L), and to add the modulo shifts to the respective transmit samples, and a linear precoder (122) configured to jointly process the resulting transmit samples based on second channel coupling information (p') that aim at effectively diagonalizing an overall channel matrix (HP') resulting from the concatenation of the linear precoder with the communication channels. The present invention also relates to a method for pre-processing signals for crosstalk mitigation. |
