Glossary Item Box

Gets or sets the array of reference preamble IQ values.

Syntax

Visual Basic (Declaration) 
Public MustOverride Property PreambleValues As Single()
C# 
public abstract float[] PreambleValues {get; set;}
C++/CLI 
public:
abstract property array<float>^ PreambleValues {
   array<float>^ get();
   void set (    array<float>^ value);
}

Property Value

The default value is an empty array.

Remarks

This is an array of floating-point values. For each preamble IQ value, there are two values in the array - first the real (I) part of the IQ value, followed by the imaginary (Q) part of the IQ value.

The array should contain an IQ value for each preamble subcarrier specified in the ResourceMap array. If the end of PreambleValues is reached but more preamble values are needed, then the analyzer loops back and starts over at the beginning of the array.

For MIMO signals that have different preamble values transmitted simultaneously on more than one transmitter antenna at the same time, the preamble IQ values array should hold all of the preamble IQ values for the first antenna, followed by all of the preamble IQ values for the second antenna, and so on.
