摘要:
Aspects of a method and system for communicating via a spatial multilink repeater are provided. In this regard, a received signal may be frequency shifted to generate a plurality of repeated signals, wherein each repeated signal may be shifted by a different frequency with respect to the received signal. Each repeated signal may comprise one or more signal components and a phase and/or amplitude of each of the components may be controlled to control a directivity of the repeated signals. Each of the repeated signals may be generated by quadrature down-converting said received signal by mixing the received signal with a first LO signal pair, up-converting the down-converted signal by mixing it with a second LO signal pair, and adding or subtracting an in-phase portion and a quadrature-phase portion of the up-converted signal.
