Adaptive receive and omnidirectional transmit antenna array
First Claim
1. A system for reducing the overall effect of intercell interference and multipath fading of mobile communication device, comprising:
- a base station for transmitting signals to a mobile communication device and receiving signals from the mobile communication device;
an adaptive directional receive antenna array coupled to the mobile communication device for receiving the transmitted signals from the base station; and
an omnidirectional transmit antenna coupled to the mobile communication device for transmitting signals to the base station.

Abstract
An adaptive antenna used in a receive only mode with a separate omnidirectional transmit antenna. The arrangement is especially effective for small, handheld wireless devices. The transmit antenna maybe integrated with the receive array by utilizing a horizontally polarized transmit and vertically polarized receiver ray. In other embodiments, the transmit antenna may be physically separate and not integrated with the receive array. In either case there is separate receive and transmit signal port as an interface to radio transceiver equipment. The use of an adaptive antenna in the receive only direction has the potential to increase forward links capacity to levels equal to or greater than reverse link capacity. This allows for a significant increase in the overall number of users that may be active at the same time in a wireless system.
