In communication systems, DAMA refers to which method of sharing a satellite channel among multiple Earth stations?

Question

Solve this multiple-choice question and choose the correct option.

Accepted Answer

Introduction / Context:DAMA (Demand-Assigned Multiple Access) is a channel allocation technique used in satellite communication to efficiently share limited satellite transponder capacity among many users. Given Data / Assumptions: Many Earth stations share a satellite. Channel resources (bandwidth, time slots, frequencies) are limited. Users require intermittent communication rather than continuous use. Concept / Approach:DAMA dynamically assigns channels to Earth stations only when needed, rather than dedicating them permanently. This improves efficiency, especially in systems where users are idle most of the time. Step-by-Step Solution: User requests channel → DAMA controller allocates slot/frequency.After use → channel released back to pool.Efficient sharing achieved without wasting capacity. Verification / Alternative check: INTELSAT and VSAT networks have used DAMA for decades to maximize resource utilization. Why Other Options Are Wrong: Decibel Attenuated Microwave Access: meaningless acronym.Digital Analog Master Antenna: unrelated to DAMA.Dynamically-Assigned Multiple Access: close but not the standard term.Distributed allocation of antennas: unrelated concept. Common Pitfalls: Confusing DAMA with TDMA or FDMA; DAMA is an allocation policy, not a modulation or multiplexing scheme. Final Answer: Demand-Assigned Multiple Access
