% 2x1D Wiener CE for OFDM systems - first 1D in time domain, followed by 1D in frequency domain
%

%               i)  Channel: exponentially decaying profile, Jakes' Doppler spectrum
%                ii) 802.11a parameters
%                iii)802.11a pilot spacing (short + long + pilot-tones, Nf=12,Nt=1), with
%                       rectangular (as the standard) or diagonal pattern.

%    i)  After time domain interpolation, more interploated channel coefficients should
%     be used in freq. domain interpolation. (changed from Ufuk's code.)
%    ii)  For the pilots pattern of 802.11a, freq. first is not an appropriate order
%       since N_f = 12 is larger than the rule-of-thumb Nyquist rate. So OneD_ft.m
%                       is NOT implemented FOR 802.11a parameters.
