Open full text 7 citations

Abstract

In this paper, the Erlang capacity of mobile protocols such as FDMA (Frequency Division Multiple Access), TDMA (Time Division Multiple Access), and CDMA (Code Division Multiple Access) systems are compared assuming perfect power control. Methods of calculating the traffic capacity of such systems are discussed. A simulation and modeling method is used and the results are compared with previous analytical methods. The simulation result is close to analytical result although a different approach is adopted. CDMA can provide up-to 20 times more traffic capacity than FDMA and 5.3 times more traffic capacity than TDMA.
