Glossary Item Box

Gets or sets a value indicating the symbol count per channel estimation CDM (Code Domain Multiplex) grouping unit used to despread this FramePart's MIMO pilot (or preamble) allocations in the code domain if they share an overlapped symbol/subcarrier allocation pattern.

Syntax

Visual Basic (Declaration) 
Public Overridable Property CdmGroupSymbolCount As Integer
C# 
public virtual int CdmGroupSymbolCount {get; set;}
C++/CLI 
public:
virtual property int CdmGroupSymbolCount {
   int get();
   void set (    int value);
}

Property Value

The default value is 1. The minimum is 1. The value can't be bigger than 1 if the pilot payload sequence is PayloadType.Unknown as we need to use reference pilots to despread the pilot in code domain. The value will be checked and coerced after Apply.

Remarks

This value is unitless.

This property is required for CDM (Code Domain Multiplex) overlapped MIMO pilot (or preamble) configurations. A value of N means that for each pilot (or preamble) subcarrier, the pilot (or preamble) values on N adjacent pilot (or preamble) symbols are used together to estimate the channel response, and this estimation result is applied to all the N adjacent pilot (or preamble) symbols.

This property along with CdmGroupSubcarrierCount decide the size of channel estimation CDM (Code Domain Multiplex) grouping unit in time domain and frequency domain.

Requirements

Target Platforms: Windows 11 Professional or Enterprise; Windows 10 Professional, Enterprise, or Education (64-bit)

Minimum Software Version Requirement: Keysight PathWave 89600 VSA Ver 29.00
