ICI Suppression for Mobile OFDM System by Using a Hybrid 2-Layer Diversity Receiver

An OFDM system is very sensitive to orthogonality relation. For a mobile wireless system, it is impossible to avoid Doppler-induced inter carrier interference (ICI). Moreover, while beyond guard interval delayed signal exists in channel, the delay-induced ICI and inter symbol interference (ISI) will occur. Although a conventional carrier diversity (CD… CONTINUE READING
