Data stream cancellation for data transmission network

A communication device, comprising:

• a data canceler that comprises:
• a first inverter circuit comprising an input coupled to a first input terminal of a data transmission network,
• wherein the first inverter circuit is configured to generate an inverted data signal based on an inversion of a first unwanted data signal supplied via the first input terminal;
• and
• a passive network comprising a plurality of passive components arranged between an output terminal of the data transmission network and an output of the first inverter circuit,
• wherein the passive network is configured to:
• receive, via the output terminal of the data transmission network, a mixed data signal comprising a target data signal and the first unwanted data signal;
• and
• combine the inverted data signal and the mixed data signal across the plurality of passive components to cancel the first unwanted data signal in the mixed data signal.
