LV Jun-zhe, ZHANG Hai-lin, HE Fei, et al. A New Adaptive Equalization with No Guard Time of OFDM[J]. Acta Electronica Sinica, 2002, 30(7): 941-944.DOI:
a method of equalization of OFDM (Orthogonal Frequency Division Multiplexing) signal is described.If the length of its cyclic prefix is larger than the delay spread of transmission channel
we can get a simple frequency equalizer to demodulate OFDM signal.However
the use of cyclic prefix degrades the efficiency of transmission greatly.For this
we give a new equalizing structure
which improves the efficiency of transmission of OFDM system.And this method is examined by computer and good characteristics are confirmed.
