%% Demodulate 2x2 HT-LTF with OFDM Symbol Offset
% Create an HT configuration object having two transmit antennas and two space-time streams.

cfg = wlanHTConfig('NumTransmitAntennas',2,'NumSpaceTimeStreams',2, ...
    'MCS',8);

%
% Generate the HT-LTF based on the configuration object.

x = wlanHTLTF(cfg);

%
% Pass the HT-LTF signal through an AWGN channel.

y = awgn(x,10);

%
% Demodulate the received signal. Set the OFDM symbol offset to 0.5, which corresponds to 1/2 of the cyclic prefix length.

z = wlanHTLTFDemodulate(y,cfg,0.5);
