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.
