Abstract: A wireless system, which minimizes nulls within the wireless system, while simultaneously providing diversity. A wireless system will now have increased capacity and coverage due to an enhanced signal to interference ratio in the areas of beam overlap. The system uses time or frequency offset on the signals input to an antenna to minimize interference in the regions of beam overlap. Additionally, polarization diversity can be introduced using Butler Matrices in conjunction with array elements to enhance the interference reduction.

Abstract: A method and apparatus for reuse of pseudo-random noise (PN) offsets within a cell of a wireless communication system such as a multi-sector CDMA system. Adaptive antenna arrays are employed to form the multiple sector areas within the CDMA cell. A forward link data channel is established between a mobile unit and a base station via sectors that share or reuse comment PN offsets, thereby providing desirable transmit diversity.

Abstract: A method, apparatus and system are provided for use in optimizing signal-to-noise ratios at remote wireless devices. A method can receive a signal over a reverse link, determine an angular power profile of the reverse link signal, and determine an antenna weighting vector for the forward traffic signal based on the angular power profile. The determination of the weighting vector can include retrieving the vector from a weighting vector table. Some methods identify boundaries of angular spreads and utilize pre-calculate weighting vectors according to the boundaries. An apparatus can include an antenna array, a wireless receiver that receives reverse link signals, a detector that detects an angular power profile of the signals, a controller that determines a weighting vector and applies the weighting vector to the antenna array when transmitting. Some embodiments are dependent on whether the forward link incorporates a common pilot or per-user pilot signal.
