Resource Unit Setup (Basic)

Index

This cell displays the index of the Resource Unit (RU) for this timeslot

State

Enable or disable the selected RU.

Right-clicking the column header of State, a popup menu will appear to facilitate you to make proper setup.

Power (dB)

Range: –60 to 0 dB.

Default: 0 dB

Enter a value to set the RU power relative to other RU. The CDP graph displays the normalized power of each RU in each timeslot after you generate the waveform. Refer to the Power Setting for the power calculation of the carriers, channels/timeslots and RUs.

Right-clicking the column header of Power, a popup menu will appear to facilitate you to make proper setup.

Channel Code

Range: 1 to 16

Default: index of the current RU

Enter a value to set the channel code of the selected RU.

Channel code is coupled with the spreading factor. Channel code can not exceed the spreading factor.

User ID

Range: 1 to 16

Default: 1

Enter a value to set the User ID of the current RU.

User ID of the current RU is coupled with the max user number for this timeslot. User ID can not exceed the max user number of the timeslot.

Modulation

Choices: QPSK | 8PSK | 16 QAM | 64 QAM

Default: 0 dB

Double-click or use the drop-down menu to set the modulation type of the selected RU.

Right-clicking the column header of Modulation, a popup menu will appear to facilitate you to make proper setup.

Spreading Factor

Choices: SF 1 | SF 2 | SF 4 | SF 8 | SF 16

Default: SF 16

Double-click or use the drop-down menu to set the spreading factor of the selected RU.

Right-clicking the column header of Spreading Factor, a popup menu will appear to facilitate you to make proper setup.

Timing Offset

Range: –8 to 8 chips

Default: 0 Chips

Enter a value to set the timing offset for the selected RU in this timeslot. If the OSR is equal to 8, 16, 24 or 32, the timing offset values increment by 0.125 chip; If the OSR is set to other values, the timing offset values increment by 1 chip. Physical channels summed in phase produce a high crest factor (high peak-to-average ratio). Offsetting the timing can minimize the crest factor. This cell is read-only for downlink timeslots. 

Right-clicking the column header of Timing Offset, a popup menu will appear to facilitate you to make proper setup.

Timing Offset property is only valid for uplink timeslots. For downlink timeslots, it is read-only. The switching point determines how timeslots 2 through 6 are allocated between uplink and downlink. Timeslots before the switching point are allocated to the uplink; timeslots after the switching point are allocated to the downlink.

Phase

Range: –360 to 360 degrees

Default: 0 degree

Enter a value to set the phase rotation for the selected RU in this timeslot. Right-click the column header of Phase, and a popup menu will appear to facilitate you to make proper setup.

Reset: Reset the phase rotation of all RUs in this timeslot to 0 degree.

Data Source

Choices: PN9 | PN15 | 0, 1 text file | Binary file

Default: 0 dB

Double-click or use the drop-down menu to set the data source for the selected RU.

PN 9

select continuous PN9 sequence numbers with random initial offset

PN 15

select continuous PN15 sequence numbers with random initial offset

0, 1 text

selects this to load a user-defined 0, 1 text file from a selected location as the data source. When this choice is selected, an Open window is displayed for navigating to and selecting the desired ASCII file (*.txt).

Binary file

selects this to load a user-defined binary file from a selected location as the data source. When this choice is selected, an Open window is displayed for navigating to and selecting the desired binary file.

Right-clicking the column header of Data Source, a popup menu will appear to facilitate you to make proper setup.

User File

If you select 0, 1 text file or binary file as the data source, this cell displays the path that you load the file from.
