👉 PST (Presentation State Transition) engineering is a methodology used in the design and development of digital communication systems, particularly in software-defined radio (SDR) and cognitive radio technologies. It focuses on modeling and simulating the behavior of system states, especially in the context of how these states transition in response to various inputs or environmental changes. PST engineering involves creating a detailed, state-based representation of the system's operational modes, including both normal and failure states. This approach allows engineers to predict system behavior under different scenarios, optimize performance, and ensure robustness in dynamic environments. By using PST models, designers can simulate complex interactions and validate system designs before physical implementation, reducing development time and costs while enhancing reliability and adaptability.
