Zusammenfassung:In this paper, frequency domain pre-equalization at the base station is studied. Some different schemes are proposed and compared for single input single output (SISO) and multiple input multiple output (MIMO) broadband code division multiple access (CDMA) systems. The proposed MIMO zero forcing pre-equalization scheme cancels completely the effect of the intersymbol interference (ISI) and provides a better performance than the other traditional schemes. Our simulation results show an appreciable performance improvement by using the proposed scheme with a very low complexity at the mobile unit.
