1. A multiple antenna system (MAS) with multiuser (MU) transmissions (“
- MU-MAS”
) comprising;
a plurality of distributed antennas all sharing the same cell ID; and
a spatial processing unit that implements open-loop or closed-loop precoding methods for interference cancellation on a plurality of waveforms being sent to or received from the plurality of distributed antennas to create multiple concurrent non-interfering wireless links with a plurality of client devices operating within the same frequency band to achieve multiplexing gain and increase capacity in wireless communications networks, wherein the number of multiple concurrent non-interfering wireless links is up to a total number of the distributed antennas.
