MULTI-ACCESS TECHNIQUE EVALUATION SIMULATOR

THIS PROJECT CONCERNS A TECHNIQUE WHICH COMBINES THE INHERENT TIME BENEFITS OF AN ANALYTIC MODELING APPROACH FOR INVESTIGATING COMMUNICATION CHANNELS WITH THE FLEXIBILITY OF A MONTE CARLO DIRECT SIMULATION APPROACH INTO A SINGLE INTEGRATED SOFTWARE PACKAGE. THE RESULTANT MATHEMATICAL MODELING TOOL IS FULLY GENERALIZED AND WILL ALLOW AN ANALYST TO EVALUATE ANTICIPATED PERFORMANCE LEVELS OF CANDIDATE MULTIPLE ACCESS COMMUNICATION SYSTEMS. THE GOAL OF THIS RESEARCH IS TO DEMONSTRATE THAT THIS HYBRID ANALYSIS TECHNIQUE PROVIDES A FLEXIBLE, ACCURATE AND RELIABLE TOOL WITHOUT REQUIRING LARGE COMPUTER RESOURCES. THIS GOAL WILL BE ACHIEVED THROUGH FLEXIBLE OPTIONS FOR SELECTING THE SOFTWARE ANALYSIS TECHNIQUE AND INNOVATIVE APPROACHES TO CHAINING DATA FLOW THROUGH THE COMMUNICATION LINK COMPONENTS. THE UNIQUE ASPECT OF THIS RESEARCH IS THE COMBINING OF THESE OFTEN COMPETITIVE APPROACHES INTO ONE FULLY FLEXIBLE SOFTWARE TOOL AS ONE INVESTIGATES THE COMMUNICATION CHANNEL OF INTEREST. THE PHASE II PROPOSED EFFORT IS CONCERNED WITH EXTENDING THE PHASE I PROTOTYPE TO PROVIDE A DYNAMIC ENVIRONMENT FOR THE TRANSMISSION SIGNAL. THE DYNAMIC MODEL WILL ALLOW ONE TO EVALUATE DETAILS OF THE MULTI-ACCESS SCHEME BETWEEN THE SPACE STATION AND FREE FLYERS WHICH ACCOUNT FOR ORBIT DYNAMICS, MULTI-PATH, RFI, ETC.
