This paper presents different spatial diversity techniques that can be employed in an OFDM based WLAN system to improve the system performance in Rice and Rayleigh channels using hard, soft quantified and soft no quantified decision. Packet Error Rate (PER) results are presented for both transmit (up-link) and receive (down-link) diversity configurations. This paper also presents some results obtained by simulation when a HIPERLAN/2 transceiver is employed.
