Design of a Combo Echo and Crosstalk Canceller in One Unit

In purposed design, we are going to design two transmission line. Now through these transmission lines, we will pass two mono signals, outputs of workspace. Then generate a stereo signal, result of crosstalk between these two transmission lines. To generate crosstalk, we are connecting these two transmission lines via a capacitor.
Now, we will first try to remove the echo from our received signal, to get echo free desired signal. And for this purpose Adaptive filter came into action. Now further main dominating factor i.e. crosstalk will also be removed. 
Our design is capable of cancelling crosstalk along with echo in NEXT and FEXT, in case of DSL, VDSL, and ADSL communication system.
