Abstract

A technology is described for a repeater having a Fourier Transform Matrix (FTM). The repeater can comprise a first set of N M-plexers having M ports on a first side of each of the first set of the N M-plexers and a single port on a second side of each of the first set of the N M-plexers; a first set of M N by N (N×N) FTMs, with each of the M FTMs in the first set having N first side ports and N second side ports; and a first inverse N×N FTM comprising N first side ports and N second side ports; an antenna port coupled to a Pth port of a second side of the first inverse N×N FTM; and a signal port at the Pth port of a first side of each of the M N×N FTMs in the first set.
