摘要

In last decade the Adaptive Antenna (AA) or smart antenna for mobile telecommunication especially for Code Division Multiplex Access (CDMA) system were developed at an extraordinary pace. Most professional people and related papers centered their attention on so-called "Optimum Combining (OC)" AA which is represented by the algorithms using Least-Mean-Square (LMS) and Recursive-Least-Square (RLS). These kinds of AA were able to provide an optimum Signal-to-Interference-plus-Noise-Ratio (SINR), through the use of a desirable antenna radiation pattern whose mainlobe pointed towards the desired signal while the nulls pointed towards the source of interference.
