%% Demodulate L-LTF
% Perform OFDM demodulation on the legacy long training field (L-LTF) of a received signal, specifying a channel bandwidth of 80 MHz.
% Retrieve the L-LTF from a very-high-throughput (VHT) waveform with a channel bandwidth of 80 MHz.

cbw = 'CBW80'; % Specify the channel bandwidth
rx = wlanLLTF(wlanVHTConfig('ChannelBandwidth',cbw));

% Get the frequency-domain signal by demodulating the L-LTF.

sym = wlanHEDemodulate(rx,'L-LTF',cbw);
