    %% Recover HT-SIG Information Bits in Perfect Channel 
%   

%% 
% Create a |wlanHTConfig| object having a channel bandwidth of 40 MHz.
% Use the object to create an HT-SIG field.
cfg = wlanHTConfig('ChannelBandwidth','CBW40');
[txSig,txBits] = wlanHTSIG(cfg);  

%% 
% Because a perfect channel is assumed, specify the channel estimate as a
% column vector of ones and the noise variance estimate as zero.
chEst = ones(104,1);
noiseVarEst = 0;  

%% 
% Recover the HT-SIG information bits. Verify that the received information
% bits are identical to the transmitted bits.
rxBits = wlanHTSIGRecover(txSig,chEst,noiseVarEst,'CBW40');
numerr = biterr(txBits,rxBits)
