Equalization of OFDM-systems by interference cancellation techniques
Martin Toeltsch, Andreas F. Molisch · 2002
Intercarrier interference can be a dominant source of errors in OFDM-systems, requiring some sort of equalization. We show that serial and parallel interference cancellation techniques, which were originally developed for CDMA multiuser techniques, can be used for OFDM equalization and are much more efficient than a brute force inversion of the channel matrix. Maximum excess delays of up to 70% of the OFDM block duration can be handled without loss of performance.
