Glossary Item Box

Gets or sets the equivalent noise bandwidth (in Hz) used when calculating power in the offset.

Syntax

Visual Basic (Declaration) 
Public MustOverride Property IntegrationBandwidth As Double
C# 
public abstract double IntegrationBandwidth {get; set;}
C++/CLI 
public:
abstract property double IntegrationBandwidth {
   double get();
   void set (    double value);
}

Remarks

If RrcFilterEnabled is false, the integrated power, and psd in the offset regions are calculated across IntegrationBandwidth. Equivalently, integrated power and psd are calculated by integrating the spectrum weighted by a rectangular window with the specified ENBW.

The typical use case for RrcFilterEnabled true is for modulation schemes where a matched set of root raised cosine filters are used on the transmit and receive side. The total response of this system is a raised cosine filter which has zero inter-symbol interference when the symbol rate of the modulation equals the equivalent noise bandwidth of the filter.

If RrcFilterEnabled is true, the offset region power results are calculated across the bandwidth of a raised cosine filter with the equivalent noise bandwidth given by IntegrationBandwidth and with the shape parameter RrcFilterAlpha. The integrated power and psd are calculated by weighting the spectrum using the frequency response of a root raised cosine filter, one of the matched pair of filters with a total response equal to the raised cosine filter.
