Abstract
Power levels for a code-division multiple access (CDMA) signal with layered orthogonal codes are displayed. When displaying power levels for multiple code layers, a power level for each active code channel is displayed using a bar. A width of the bar indicates in which code layer each active code channel is active. A color of the bar also can be used to indicate in which code layer each active code channel is active. For example, a power level for each active code channel is displayed using a hollow bar and a power level for each inactive code channel is displayed using a line. Alternatively, a power level for each inactive code channel is displayed using a hollow bar and power level for each active code channel is displayed using a solid bar. When displaying a power level for a single code layer, a power level for each active code channel in the single code layer is displayed using a hollow bar, and a power level for each code channel which is inactive in the single code layer is displayed using a line. Alternatively, when displaying a power level for a single code layer, a power level for each active code channel in the single code layer is displayed using a solid bar, and a powe…
