Abstract
Improved methods and apparatuses are provided to address a potential “hidden beam problem” in wireless communication systems employing smart antennas. The improved methods and apparatuses utilize complementary beamforming (CBF) techniques, such as, for example, Subspace Complementary Beamforming (SCBF), Complementary Superposition Beamforming (CSBF) and/or Single Beam Complementary Beamforming (SBCBF) techniques.
Claims20
A method, comprising:
- determining at least one signal operatively configured for subspace complementary beamforming (SCBF) in a wireless communication system;
- and
- generating the at least one signal such that the signal is operatively configured to cause a smart antenna to perform said SCBF and transmit at least one complementary beam.
A method, comprising:
- determining at least one signal operatively configured for complementary superposition beamforming (CSBF) in a wireless communication system;
- and
- generating the at least one signal such that the signal is operatively configured to cause a smart antenna perform said CSBF and transmit at least one complementary beam.
