CDE Composite (TD-SCDMA)

CDE Composite shows the Code Domain Error (CDE) value for each active code channel for all code layers (Spread Code Length) at the specified sub-frame number and timeslot. Also the CDE value for each inactive code channel at the lowest code layer is provided. The CDE of a particular code channel is a measure of the error power in a code channel relative to the total signal power.

Display Format

The data is shown in a multi-color format that assigns a unique color to each code layer and then fills each related active code channels with the same color. This makes it easy to visually identify and distinguish the active code channels for a given code layer (Spread Code Length). The colors are also user definable (see Display Preferences > Color tab).

Use the CDE Layer trace data display to view only one code layer (Spread Code Length or Symbol Rate) at a time.
