wlanSegmentDeparseSymbols

Segment-deparse the symbols in four OFDM symbols for a VHT configuration with a channel bandwidth of 16 MHz and 3 spatial streams.

Define the input parameters. Since the channel bandwidth is 16 MHz, set the number of data subcarriers to 468 and the number of frequency segments to two.

chanBW = 'CBW16';
numSD = 468; 
numSym = 4;
numSS = 3;
numSeg = 2;

Create the input sequence of symbols.

data = randi([0 1],numSD/numSeg,numSym,numSS,numSeg);

Segment-deparse the symbols into data subcarriers. The first dimension of the parsed output accounts for the total number of data subcarriers.

deparsedData = wlanSegmentDeparseSymbols(data,chanBW);
size(deparsedData)

ans = 1×3

   468     4     3

Get the symbol order after stream deparsing a sequence for a VHT configuration with a channel bandwidth of 160 MHz and one spatial stream.

Define the input parameters. Since the channel bandwidth is 160 MHz, set the number of data subcarriers to 468 and the number of frequency segments to two.

chanBW = "CBW160";
numSD = 468;  
numSym = 1;
numSS = 1;
numSeg = 2; 

Create the input sequence of symbols.

sequence = (1:numSD*numSym*numSS).';
inp = reshape(sequence,numSD/numSeg,numSym,numSS,numSeg);

Segment-deparse the symbols. The output is a column vector with the sequence order of the symbols.

deparsedData = wlanSegmentDeparseSymbols(inp,chanBW);
deparsedData(1:10)
