Multiple receiving antennas increase the capacity of wireless medium by admitting multiple users in the SDMA mode and by reducing channel selectivity. Additionally, spectral diversity may be exploited via a frequency spreading of symbols in order to combat frequency selectivity. The structure of a frequency spreading allows to train the channel equalizer / multiuser interference chancellor with no substantial overhead. A multicarrier modulation scheme with frequency spreading is proposed which yields a simple and data efficient detection of a desired user due to its spreading signature only. A numerical study shows this method suitable for broadband wireless applications.
