%% Generate HT-LTF with Four Space-Time Streams % Generate an HT-LTF having four transmit antennas and four space-time % streams. %% % Create a |wlanHTConfig| object having an MCS of 31, four transmit % antennas, and four space-time streams. cfg = wlanHTConfig('MCS',31,'NumTransmitAntennas',4,'NumSpaceTimeStreams',4) %% % Generate the corresponding HT-LTF. hltfOut = wlanHTLTF(cfg); %% % Verify that the HT-LTF output consists of four streams (one for each % antenna). size(hltfOut) %% % Because the channel bandwidth is 20 MHz and has four space-time streams, % the output waveform has four HT-LTF and 320 time-domain samples.
