Abstract:

The lattice reduction (LR) aided schemes were adopted in the zero forcing (ZF) algorithm (LR ZF) in rich multipath mobile communication environments of code division multi-access (CDMA) systems. The performance of LRZF was simulated and analyzed in LASMAX systems. The results verify that the systems' performance is improved highly, particularly in high SNR, at the expense of a little complexity increase. So LR algorithm can be adopted in mobile communication systems with multipath channel.
