1. A multiplexing method for operating a Multiple Input Multiple Output (MIMO) system in a multipath environment, the MIMO system comprising a transmit subsystem comprising two or more transmit antennas and a receive subsystem comprising two or more receive antennas, the multiplexing method comprising:

  • in a training mode,activating a first transmit antenna to transmit a predetermined pilot signal, determining a first angle of arrival (AOA) and a first time of arrival (TOA) from one or more signals received at the receive subsystem;

    activating a second transmit antenna to transmit a predetermined pilot signal, and determining a second angle of arrival (AOA) and a second time of arrival (TOA) from one or more signals received at the receive subsystem;

    deriving a spatial frequency and temporal frequency transfer function from the signals received at the receive subsystem;

    in an operating mode,using the spatial and temporal transfer function to discriminate signals received at the receive subsystem.
