摘要： Systems and methods can operate to improve the communication bandwidth in communication systems. Communication systems can use new forward error correction (FEC) algorithms to increase communication bandwidth. New FEC algorithms can also enable the use of other modulation formats to further improve communication bandwidth. Communication devices that can select from a plurality of FEC algorithms and modulation formats can maintain backward compatibility with the deployed FEC algorithms and modulation formats implemented in legacy communication devices while realizing increased communication bandwidth.

摘要： Systems and methods can provide for packet-rate policing and admission control with optional stress throttling. In some implementations, a broadband device can monitor bandwidth usage and respond after exceeding a maximum packet-rate threshold based on a per-channel basis. In other implementations, a broadband device can monitor bandwidth usage and respond after exceeding a maximum packet-rate threshold based on a per-service-flow basis. In additional implementations, a broadband device processor can feedback data to the packet-rate policer to throttle the packet rate based on processor utilization. Policing data traffic based on packet-rate instead of bandwidth can increase flexibility to service providers as an increasing number of services are deployed to users.

摘要： Methods, systems, and apparatuses can provide a plurality of RF channels and outputs using digital modulation and combining. In various examples, generation of digital IQ packetized data in combination with digital switching can increase the number of RF modulated channels, optimize broadcast transmission and/or provide transmission resiliency.
