Abstract:
1. An area-designing apparatus having processing means for simulating a CDMA mobile communication system, the processing means comprising: means for placing a plurality of communicating mobile stations corresponding to traffic distribution information on a map; means for deciding, for each mobile station, a base station to which the mobile station is radio-linked; means for calculating transmission power of a signal that each base station transmits to each of the mobile stations that are radio-linked thereto so that a ratio of reception power of a signal to reception power of interferences converges to a predetermined value, said reception power of a signal being that of a signal that each mobile station receives from the base station radio-linked thereto, said reception power of interferences being that of interferences that the same mobile station receives from the base station radio-linked thereto and from each of the other base stations, converges to a predetermined value; means for successively selecting, while each base station is transmitting the calculated transmission power signal, each of a plurality of evaluation positions on the map which are independent from positions at which the mobile stations are placed on the map; and, means for calculating reception power of a signal received by an additional evaluation mobile station placed on the map at each selected evaluation position, the signal being received from the base station that the additional evaluation mobile station is radio-linked thereto, and for calculating reception power of interferences received by the additional evaluation mobile station from all of the base stations including the base station to which the additional evaluation mobile station is radio-linked; wherein communication quality at each evaluation position is evaluated corresponding to the calculated reception signal power and the calculated reception power of the interferences.
