Simulation tool for the assessment of adaptive techniques to improve the TETRA air interface

This paper presents an evaluation system for the dynamic control of TETRA radio systems. Detailed link-level simulation results are controlled by event driven system level simulations which allows the operation of the overall system to be emulated accurately but with relatively low computational overhead. The system is particularly useful for studying the behaviour of adaptive algorithms when the system is in a transition between different states, and for predicting the quality of service delivered to the end user
