Generate the corresponding VHT waveform. cfg = wlanVHTConfig('MCS',8,'ChannelBandwidth','CBW160','NumTransmitAntennas',2,'NumSpaceTimeStreams',2); txSig = wlanWaveformGenerator([1;0;0;1],cfg); %% % Determine the component PPDU field indices for the VHT format. ind = wlanFieldIndices(cfg) %% % The VHT PPDU waveform is comprised of eight fields, including seven % preamble fields and one data field. %% % Extract the VHT-STF from the transmitted waveform. stf = txSig(ind.VHTSTF(1):ind.VHTSTF(2),:); %% % Verify that the VHT-STF has dimensions of 640-by-2 corresponding to the % number of samples (80 for each 20 MHz bandwidth segment) and the number % of transmit antennas. size(stf)
