Glossary Item Box

Gets or sets a value indicating the subcarrier 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 MustOverride Property SubcarrierCountPerChannelEstimationUnit As Integer
C# 
public abstract int SubcarrierCountPerChannelEstimationUnit {get; set;}
C++/CLI 
public:
abstract property int SubcarrierCountPerChannelEstimationUnit {
   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

The values are 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) symbol, the pilot (or preamble) values on N adjacent pilot (or preamble) subcarriers are used together to estimate the channel response, and this estimation result is applied to all the N adjacent pilot (or preamble) subcarriers.

This property along with SymbolCountPerChannelEstimationUnit 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)
