The invention relates to a CDMA cellular radio system, comprising in each cell at least one base station (BTS) connected to the mobile stations (MS1, MS2) in the cell, in which system a data signal of each user generated with a given bit rate is multiplied by a spreading code generated with a bit rate considerably higher than the bit rate of the data signal, the ratio between the data signal and the spreading code forming the spreading ratio of the connection, and in which system signals multiplied by the spreading codes of several users are transmitted on the same frequency band. To improve the quality of a connection between a mobile station and a base station, the spreading ratio of the connection between the base station (BTS) and the mobile station (MS1, MS2) is adjusted during the connection on the basis of signal quality. |
