A method of equalizing an OFDM signal received over a transmission channel defined by a channel matrix includes: windowing the received signal in the time domain with at least two different tapers to obtain at least two tapered received signals; stacking the tapered received signals in the form of a joint matrix equation [ y 1 ⋮ y γ ⋮ y Γ ] = [ D 1 ⋮ D γ ⋮ D Γ ] ⁢ y = [ D 1 ⋮ D γ ⋮ D Γ ] ⁢ ( Hx + Φ ) with y being the received signal, Γ being the number of tapers, Dγ being the γth taper in form of a diagonal matrix, yγ being the γth tapered received signal, H being the channel matrix, x being the time domain transmitted signal, φ being optional noise; and solving said joint matrix equation for x as a least squares problem.
