802.16 OFDM Standard Setups/Presets Table.
: SeeFs/BW is the ratio between OFDM FFT sample rate ("Fs" in the standard) and the nominal channel bandwidth ("BW" in the standard). See Nominal Bandwidth. This ratio is referred to as "n" in the standard. The value is generally a number slightly larger than one.
Specific values supported (via radio buttons) are
, and .In addition, arbitrary value between 0.5 and 2 are possible by checking
and specifying the value in the text box.The
default is auto-detect based on BW. For auto-detect, the Manual Fs/BW Ratio checkbox is greyed. The image below shows a check in the checkbox. This will manually override the auto-detect setting. The selected value of the manual Fs/BW Ratio shown here is , which is the default manual setting.
Check the
check box.Select one of the five preset ratios or
and enter a value between 0.5 and 2 in the text box.Check to see if observing other Trace Data graphs demodulates the signal. The
or trace data images are useful. If the signal is demodulated, the Constellation diagram will be correct and the will show low errors.See Also
