Abstract :
Most cellular radio systems provide for the use of transmitter power control to reduce co-channel interference for a given channel allocation. Efficient interference management aims at achieving acceptable carrier to interference ratios (CIR) in all active communication links within the system. This paper is a study of the effect of decreasing the power from interferer sources in a frequency-reuse system on the co-channel interference and cellular channel capacity. It also provides a comparative cumulative distribution function (CDF) probability performance study for the AMPS (Advanced Mobile Phone System) and GSM (Global System for Mobile Communications) systems at the pertaining CIR levels of 18 dB and 11 dB respectively. A 7 cell cluster is used throughout the simulations, in line with the AMPS system. However a 3 cell cluster is used for the GSM frequency-reuse model
