Abstract

In the IEEE802.11n WLAN standard, orthogonal frequency division multiplexing (OFDM) modulation is employed. Diversity techniques are implemented to overcome multipath fading in the OFDM systems. A fractional sampling (FS) scheme is one of the diversity techniques with a single antenna. This scheme can also be applied in a MIMO-OFDM system to increase its capacity. In this paper, the effect of FS in a WLAN system following the IEEE802.11n standard is investigated through experiments. Numerical results through the experiments indicate that diversity gain through FS can be obtained in the NLOS conditions.
