TDMA SATCOM System Simulation.
Abstract
A flexible system simulation program was developed that provides the capability of investigating and demonstrating the operational potential achievable when the RADC development TDMA technology is applied to a wide variety of satellite or relay communications requirements. The systems to be simulated consist of a large number of low-duty-cycle communication links. Up to 2500 users and 1250 links can be simulated in any connectivity. For each link the data rate, burst rate, and average number of calls per second can be separately specified. Eight priorities can be simulated for any call. Each user is separately simulated in terms of his state, e.g., waiting for a channel assignment, establishing contact with the destination user, etc. Various user reactions are also involved. The arrival time of calls is Poisson with the distributed parameter determined by the average number of calls per link. Call durations are exponentially distributed. The software simulates frame-by-frame, the orderwire messages from users to NCT and from NCT to users in a buffer which is the interface between the two halves of a software namely the Network Control Software (NCS) which simulates the NCT allocation algorithm, and the Simulation Software (SS) which models the user. Appropriate statistics are gathered for each run, e.g., average waiting time, blocking probabilities, average frame occupancy, etc.
