Adaptive beamforming techniques for OFDM based WLAN systems: a comparison between RLS and LMS

This work presents an study of different adaptive filter algorithms, RLS and LMS, applied in OFDM based WLAN systems. In the simulations, we use Hiperlan/2 standard. In a WLAN environment we can fin a desired signal, interfering signals and noise. In this kind of environment, we have used smart antennas in order to improve radiation diagram and signal/interference ratios. Finally, we compare results of RLS and LMS beamforming.
