    function lstf = lstfSequence()
%lstfSequence L-STF subcarrier sequence
%
%   Note: This is an internal undocumented function and its API and/or
%   functionality may change in subsequent releases.
%
%   LSTF = lstfSequence() returns the sequence used for 20 MHz L-STF as 
%   per equation 20-8 in IEEE Std 802.11-2012 pg. 1695.
