Publication number: 20240121145Abstract: To provide improvements in crest factor reduction in a distributed communication system, CFR configuration parameters can be determined based on communication signals received from a base station entity and distributed to node(s) of the distributed communication system. CFR engine(s) in the node(s) may perform CFR based on the CFR configuration parameters, and/or may adjust their CFR engine(s) based on signal parameters and/or operating parameters of a power amplifier coupled to a respective CFR engine. Some or all CFR processing may be offloaded from a node and assigned to optical transport card(s) of the system controller based on a processing bandwidth associated with the optical transport card(s).Type: ApplicationFiled: October 6, 2023Publication date: April 11, 2024Applicant: CommScope Technologies LLCInventors: Samuele Brighenti, Gabriele Moroni, Massimo Del Prete, Rainer Friedrich, Patrick Braun, Peter Schmid
