This paper introduces basic capacity calculation methods for circuit switched, multiple-beam, Low Earth Orbit (LEO) communication satellites that use MF-TDMA and MF-CDMA schemes. Capacity is defined as the number of simultaneous duplex channels that a satellite can support for a given data rate and bit error rate. This paper integrates the bandwidth limit and the power limit on capacity, and derives the equations by which the capacity of a MF-TDMA or a MF-CDMA system can be calculated using key system parameters. Therefore, these methods enable system designers to quickly estimate the communication system capacity when key system parameters are known.
