Abstract :
In a time division multiple access (TDMA) system, each channel may have more than one time slot to serve more than one user. Six time slot assignment techniques are presented. A discrete event stochastic simulation study is performed on a 120° sectored system. The simulation employs the “blocked calls cleared” traffic model and a log-linear path loss propagation model. Only the down link is considered. The results of comparing the performance of the six techniques and of investigating the effect of the number of time slots per frame and the maximum acceptable interference level are presented
