In the CDMA cellular mobile communication systems, the connection between base and mobile station has a forward link from base station to mobile station. Four channels of forward link, pilot channel, sync channel, paging channel, traffic channel, have an absolute influence on forward coverage and speech quality. And overhead channels(pilot, sync, paging) are assigned output at the adequate rate to optimize the structure of coverage and to minimize the influence of neighbor base station. And the quality of forward link depends on the size of received field strength, as well as Ec/Io which includes both self signal and all noise factors affecting self signal is the main standard in order to decide the coverage and quality of forward link. In this paper, in order to improve a performance of forward link systems in the mobile communications using CDMA, I examine influencing factors in forward links, and measure at LAB., and analyze their results. As the results, I confirm that identify their effect.
