Interference Reduction for Multiple Signals

Apparatus for reducing interference in at least two received signals, the apparatus comprising:

• an adaptive array with at least two input signals configured to generate an adaptive array output signal, the at least two input signals are derived from the at least two received signals that were transmitted from one or more transmit antennas at a common transmitter end in a common frequency channel, the transmitted signals were formed by transmitting an at least one first signal and an at least one second signal, the adaptive array output signal is made up of the at least one first signal and the at least one second signal with reduced interference, wherein the adaptive array is designed to reduce interference in the at least one first signal, and
• at least one separator to retrieve one or more of the at least one first signal and the at least one second signal from the adaptive array output signal.

Apparatus for reducing interference in K received signals, the apparatus comprising:

• an adaptive array with at least K input signals configured to generate L adaptive array output signals, the at least K input signals are derived from the K received signals that were each transmitted from a separate one of K transmit antennas at a common transmitter end in a common frequency channel, the K transmitted signals were formed by transmitting L signals, L is at least 2, K is at least L, the L signals are each made up of a different one of an L at least one first signals and an L at least one second signals, the L adaptive array output signals are each separately made up of the associated different one of the L at least one first signals and the L at least one second signals with reduced interference, wherein the adaptive array is designed to reduce interference in the L at least one first signals, and
• at least one separator to retrieve one or more of the L at least one first signals and the L at least one second signals from one or more of the L adaptive array output signals.
