Abstract
A transceiver includes a transmission chain, a reception chain, an interference suppression module and a processor. The transmission chain transmits a downstream signal to a communication network. The reception chain receives an upstream signal including (i) upstream transmissions originating by client devices, and (ii) an interference signal created by leakage and reflections of the downstream signal. The reception chain includes a configurable switch for connecting or disconnecting the upstream signal. The interference suppression module applies to the downstream signal a filter response function for generating an interference suppression signal to be subtracted from the upstream signal at a selected suppression point. The processor estimates the filter response function by monitoring the upstream signal while toggling the switch to connect and disconnect the upstream signal, and, sets the switch to connect the upstream signal and configures the interference suppression module to apply the filter response function to the downstream signal.
