Abstract:
1. A method for displaying power levels of code channels of a CDMA (Code Division Multiple Access) signal, said code channels having different spreading factors, comprising: receiving the CDMA signal; measuring the power levels of the code channels of the CDMA signal; displaying the measured power levels of the code channels for a specified base spreading factor in a diagram; and marking those code channels, which provide an alias power level, wherein a code channel provides an alias power level relating to the specified base spreading factor when the code channel with the specified base spreading factor is inactive, and a code channel of a higher spreading factor corresponding thereto is active, when measuring a CDMA signal from a transmitter with a first antenna and a second antenna, which use mutually orthogonal codes, marking a code channel with the spreading factor of the first antenna, in which an alias power level occurs, which is an actual power level of an active code channel of the second antenna, differently from a code channel with an alias power level, which is an actual power level of a code channel with a higher spreading factor of the same antenna.
