Adaptive Array Antenna for Mobile & Satellite Communication

To achieve the ambitious requirements introduced for future wireless systems, new intelligent or self-configured and highly efficient systems will most certainly be required. In the pursuit of schemes that will solve these problems, attention has recently turned to spatial filtering methods using advanced antenna techniques: adaptive or smart antennas. Filtering in the space domain can separate spectrally and temporally overlapping signals from multiple mobile units, and hence the spatial dimension can be exploited as a hybrid multiple access technique complementing FDMA, TDMA and CDMA.
