%% Demodulate L-LTF for Non-HT Format Transmission
% Demodulate the L-LTF used in a non-HT OFDM transmission, after passing the L-LTF through an AWGN channel.
% Create a non-HT configuration object and use it to generate an L-LTF signal.

cfg = wlanNonHTConfig;
txSig = wlanLLTF(cfg);

%
% Pass the L-LTF signal through an AWGN channel. Demodulate the received signal.

rxSig = awgn(txSig,15,'measured');
y = wlanLLTFDemodulate(rxSig,'CBW20');
