Abstract :
A blind second order statistical (SOS) subspace based channel identification and equalization technique is introduced and investigated for bandwidth efficient orthogonal frequency division multiplexing (OFDM) systems. A suitable zero-forcing linear equalizer (ZF-LE) is also proposed. Simulations show that identification and equalization is possible with only a small number of short length OFDM symbols
