0000 Select the payload data source. The 'Data Type Entry'
window will open to allow the selection.
Payload
Length
(Bytes)
Minimum: 1 1 This is a read-only parameter. It shows the length in
bytes that is used for the modulation on the physical
layer. It is coupled with 'Modulation Type', 'Coding
Type', 'Coding Rate Type' and 'OFDM Symbol Length'
Burst Type Burst Burst This is a read-only parameter.
Modulation
Type
BPSK |
QPSK |
16QAM |
64QAM
QPSK Selects the type of modulation. It is coupled with
'Coding Rate Type'.
Coding Type RAW |
RS-CC
RS-CC Select Coding type. It is coupled with 'Coding Rate
Type'.#RAW: no coding is done. The data bits are
directly sent into the modulator.#RS-CC:
Concatenated Reed-Solomon-convolutional code is
used.
Coding Rate
Type
N/A | 1/2 |
2/3 | 3/4
1/2 Select the coding rate. It is related to 'Modulation
Type' and 'Coding Type'. Only appropriate options will
be shown.
DIUC or
UIUC
0 to 15, step
size 1
1 Set Downlink Interval Usage Code (DIUC) for
downlink or Uplink Interval Usage Code (UIUC) for
uplink.
OFDM
Symbol
Length
Minimum: 1 1 Set how many OFDM symbols are being modulated.
The maximum value is determined based on 'Frame
duration', 'Bandwidth' and 'G '(CP Time) in the Project
View.
