Figure 6

Capacity gain improvement from the zero-forcing ( ZF ) and signal-to-jamming noise ratio ( SJNR ) beamformers over the basic IEEE802.11s access scheme. The results are shown for a varying signal-to-noise ratio (SNR) and for a distance d = 60m and d = 100m between the Relays. The curves ZF vs. Basic access and SJNR vs. Basic access indicate the capacity improvement of the ZF and SJNR beamformers over the basic IEEE802.11s access scheme. In this situation, both the SJNR and ZF beamformers show significant capacity gain improvement compared to the basic access scheme. Moreover, the SJNR outperforms the ZF beamformers in the low-SNR region (< 15 dB).
