| Abstract(in English) | We investigate link capacity increasing effects by expanding radio band width of CDMA system using computer simulations. Number of the radio propagation paths, the normalized variance of shadow fading, the correlation coefficient of shadow fading between the different base stations, ahd the path loss exponent are the main parameters in this investigations. There are two reasons for increasing the link capacity by radio band width expansion. One is increasing the number of the radio propagation paths, and the other is received interference power smoothing effects. By employing Wide-band CDMA, where band width is 4 times wider than that of Narrow-band CDMA, the link capacities increase in number of the maximum users about 20-300% comparing to the narrow band CDMA. |
