Coding Rate Coding Rate is the ratio of useful data bits to total transmitted bits in an encoded communication system. Protocol Cognitive Radio A radio system capable of autonomously sensing its RF environment and dynamically reconfiguring its own transmission parameters — frequency, power, modulation, bandwidth — in response to detected spectrum occupancy and… Concept/Framework Coherent Optics A modulation and detection technique that encodes data across both the amplitude and phase of an optical signal and uses a local reference laser at the receiver to precisely detect… Concept/Framework Collision Domain Collision Domain is the set of network nodes where simultaneous transmissions can interfere with one another on a shared medium. Concept/Framework Command and Data Handling Command and Data Handling is the spacecraft or remote-system function that routes commands, collects data, and manages onboard data flow. Software Committed Information Rate Committed Information Rate is the guaranteed average data throughput that a service provider commits to deliver over a defined period or service path. Operations Communications Payload Communications Payload is the payload portion of a spacecraft or platform that performs the communications mission. It handles the useful communications function of the asset. Hardware Confederations Confederations are groups of autonomous systems or organizations that cooperate while retaining their own control and policy independence. They combine coordination with autonomy. Concept/Framework Configuration Management Configuration Management is the process of defining, tracking, and controlling system settings and versions so systems remain consistent and manageable. It supports repeatable operations. Operations Congestion Control Congestion Control is the set of mechanisms used to prevent or reduce overload in a network or transport system by regulating traffic flow. Protocol
