Non-linear pre-coder having separate modulo decision

摘要

present invention relates to a signal processing unit for preprocessing the signal to crosstalk mitigation (120). According to an embodiment of the present invention, the signal processing unit, individual for each transmit sample to be transmitted through the respective communication channel (H) based on the first channel binding information (L) (U) determining the modulo shift (delta), and configured modulo unit to adding modulo shift the respective transmission sample (121), a transmission sample obtained as a result from the connection of the linear precoder of the communication channel linear precoder configured to process jointly on the basis of 'the second channel binding information that aims to effectively diagonal of the (.rho entire channel matrix (HP)' occurring) and (122) ,including. The present invention also relates to a method for pre-processing signals for crosstalk mitigation.
