...We consider a typical urban environment where the RMS delay spread is O=IW . Thus, the normalized RMS delay spread is alT=I.Z5 . The 4-stage LSFE has the best performance with SNR gains of around 4 .4dB and 1.4dB over the I-stage and 2-stage LSFE at BER=Ze-4, respectively....

...Comparing fig.6 to fig.2, we see that at BER=Ze-4, the I-stage and 4 -stage STBC LSFE structures have SNR gains of ahout 4.2dB and 2dB over their uncoded LSFE equivalents, respectively....

...The last stage of 4 -stage LSFE provides similar performance to its first stage, subject to error propagation intrcduced by imperfect interference cancellation....
[...]
...Fig.4 demonstrates the impact of channel estimation error on performance of I-stage and 4 -stage LSFE, with the same configuration as fig.2....
[...]
...In particular, the BER of the 4 -stage LSFE structure is about 25 times lowerthan that ofthe I-stage LSFE at O/T=Z....

...En effet il est connu [67], que les filtres égaliseurs sont plus simples à mettre en œuvre dans le domaine fréquentiel du fait de l’implémentation par bloc, et que leur convergence est plus rapide dans ce domaine que dans le domaine temporel [1][2]....

...Several variations of orthogonal frequency-division multiplexing (OFDM) have been proposed as effective anti-multipath techniques, primarily because of the favorable trade-off they offer between performance in severe multipath and signal processing complexity [ 1 ]....
