1. A base station configured to process signals received from a plurality of wireless terminals, the base station comprising:

  • a memory;

    one or more computer programs stored in the memory; and

    one or more processors that, in response to executing the one or more computer programs;

    combine a plurality of constituent signals to produce a synthesized received signal;

    subtract the synthesized received signal from a received signal to produce a residual signal;

    scale the residual signal to produce a scaled residual signal;

    combine the scaled residual signal with each of the plurality of constituent signals to form a plurality of interference suppressed constituent signals;

    time-advance the plurality of interference suppressed constituent signals to produce a plurality of time-advanced signals; and

    combine the plurality of time-advanced signals corresponding to a first user to produce a first combined user signal.
