Abstract

Aspects of a method and system for a low-complexity multi-beam repeater may include receiving one or more information signals at one or more receiver antennas, and receiving one or more local oscillator control signals via an out-of-band link. The one or more received information signals may be demodulated to one or more intermediate-frequency signals via one or more frequency carrier signals, wherein the frequency carrier signals may be controlled by the one or more received local oscillator control signals. One or more intermediate-frequency signals and/or one or more signals generated from the one or more intermediate-frequency signals may be modulated to one or more radio-frequency signals via the one or more frequency carrier signals. One or more transmit signals comprising at least one of the one or more radio-frequency signals may be transmitted via one or more transmit antennas.
