Abstract (en)

[origin: WO0215506A1] The present patent publication discloses a method and apparatus for realizing a self-compensating bandstop filter on a digital communications channel. According to the method, the signal is subjected in the transmitter to bandstop filtering (H(z<-1>)) and precoding (K(z<-1>)) using the Tomlinson principle so that a common computing engine is used for both the bandstop filtering and the precoding operations.
