Abstract

In this paper, the performance of different call admission control (CAC) algorithms of a direct sequence code division multiple access (DS-CDMA) system are compared under barrage jamming in an urban environment. Only the uplink circuit-switched speech traffic was inspected. The differences between the algorithms were compared through simulations and it was noticed that the performance of the CAC algorithms declined rapidly when jamming was increased. Especially the power based CAC algorithm turned out to be very sensitive to jamming.
