CDMA Measurements - Screens and Control Fields

CDMA Measurements

The order selected depends on the data type. A Walsh order of 1 (one), will result in a channel size of 128. This size excludes all other channel numbers from the transmission. However, a Walsh order of 2, on any of the 4 possible Walsh codes at that level (3, 1, 2 or 0)) reserves all the channels which can be generated from this channel, using the bit reverse algorithm, on Walsh orders 2 through 7.

This is shown in Figure 5-10, where the channel 1 has been selected with Walsh order 2. The shaded box indicates all the channels which will be assigned this code set. The Channel size indicates the number of Walsh orders implicated in the original Walsh order/Walsh code selection.

Available Measurements in the Code Domain

The following measurements may be selected from within the Code

Domain screen:

Power

Fast Power

Complex Power

Power & Noise

Fast Power Synchronize

Channels are indicated both by the selected number (0-127) as well as by the Walsh order to which they have been assigned or the channel size, depending on your selection.

The Code Domain may be viewed either in the Bit Reverse ordering as shown in Figure 5-11or using the Hadamard ordering, as shown in Figure 5-12.
