  • Vertical adaptive antenna array for a discrete multitone spread spectrum communications system
    Patent number: 7333531
    Abstract: Two or more antenna elements are arranged in the vertical direction to give vertical spatial adaptivity to a wireless discrete multitone spread spectrum communications system. The system is based on a combination of Discrete Multitone Spread Spectrum (DMT-SS) and multi-element adaptive antenna array technologies. This enables the automatic positioning of a beam in the vertical direction to position nulls where interferers are to located on the same azimuth but are separated in elevation.
    Type: Grant
