Property Value
The default value is -3.125% of the IFFT time length, if the GuardInterval is greater than or equal to 1/16. The default value is -GuardInterval*100/2 if the GuardInterval is less than 1/16. The maximum value is 0, and the minimum is -GuardInterval*100.Remarks
An OFDM symbol consists of a "useful" portion, and a guard interval or "cyclic prefix" that is prepended to the useful part. Normally, the guard interval is skipped over and ignored by the receiver, so that the analysis uses the last part of the symbol time. This is so that multi-path distortion does not interfere with demodulating the signal. However, it is often useful to move the analysis time backwards, so that not all of the guard interval is ignored. This may help the analysis avoid the discontinuities between OFDM symbols. SymbolTimeAdjustment allows the offset into the symbol to be moved backwards.
The SymbolTimeAdjustment is reset to the default value whenever the GuardInterval is changed.
