An initial evaluation of FDMA/TDMA and CDMA architectures for the Aeronautical Mobile Satellite Services (AMSS) is outlined in this study. Key factors leading to capacity evaluation using the two accessing schemes are evaluated. Factors include user information rate, transmission filtering roll off factors, frequency band available, frequency reuse, outside cell interference factor, cell size, required Eb/No, soft handoff factor, polarization, and power control error. The purpose of this study is to help in evaluating what systems are capable in servicing the aeronautical mobile users within the Aeronautical Telecommunications Management (ATM). Standard capacity models for CDMA and TDMA were used that are sufficient for initial evaluations, while recommendations are put forth for a more detailed model to use for future studies based on work done previously. Finally, considerations for implementing those systems in simulations are stated.
