| dcterms.abstract | Frequency reuse increases the capacity of a cellular system but results in co-channel interference. Several power control schemes to optimize the transmitter power in a TDMA system has been investigated in [1], [2], [3]. However, the convergence speed to obtain the optimum value is too slow to be acceptable in a real cellular system. A new algorithm, that improves the convergence speed is developed. Furthermore, the developed algorithm removes the problem of high transmit power in the iteration formula found in [2]. The developed algorithm has been applied to both single and multi-cell CDMA system. A large number of simulation results are reported in this dissertation. It is shown that an error of less than 1 dB to the optimum C/I value is usually obtained. The performance of this algorithm in the presence of fading is evaluated. The dynamic system behaviour when a new user enters the system as well as when an existing user leaves the system is also studied. It is found that the convergence to an optimum C/I value is slower when a new user enter the system. | en_US |
