In this regard, in one example, an interference signal offset circuit is provided in an RAU to offset interference products leaked from a downlink path to an uplink path. An offset signal generation circuit is configured to generate at least one uplink interference offset signal based on the interference products leaked from the downlink path. A signal summing circuit is configured to combine the at least one uplink interference offset signal with an uplink signal received on the uplink path, thus offsetting the interference products in the uplink signal. By providing the interference signal offset circuit in the RAU to offset the interference products on the uplink path, it is possible to provide more implementation flexibility for the RAU without degrading the uplink signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Offsetting unwanted downlink interference signals in an uplink path in a distributed antenna system (DAS)","description":"Offsetting unwanted downlink interference signals in an uplink path in a distributed antenna system (DAS) is disclosed.
