is used to select the sub-carrrier for your TEDS demodulation analysis. For example, you can view a particular subcarrier in your constellation diagram. See TEDS Subcarriers to learn more.
TEDS is based on variable subcarrier/channel bandwidths of 25, 50, 100, and 150kHz, with burst uplink and continuous downlink slot formats. In particular, the Normal Downlink, Normal Uplink, and Control Uplink slot formats can use a 25kHz bandwidth, 50kHz bandwidth, 100kHz bandwidth, or 150kHz bandwidth, while the Random Access slot format can only use a 25kHz bandwidth.
The number of subcarriers in a signal depends on the channel bandwidth selected. The table below shows the number of subcarriers for each channel bandwidth.
|
Channel Bandwidth |
Number of subcarriers |
|---|---|
|
150 kHz |
48 (-24 to 24) |
|
100kHz |
32 (-16 to 16) |
|
50kHz |
16 (-8 to 8) |
|
25kHz |
8 (-4 to 4) |
