| Abstract | ||
| Over the last few years, the number of subscribers to wireless services has increased at an explosive rate. Smart-antenna technology compared to conventional antenna has the ability to increase the number of simultaneous users, and satisfy the requirements of spectral efficiency, and coverage in wireless communication systems. In this paper the radiation pattern and performance of linear smart antenna array is investigated by considering multiple directions of arrivals of signals. The simulations done confirmed that smart antenna systems using Least Mean Square (LMS) algorithm are able to adjust their pattern to enhance desired signals, and reduce interference. The results also show that smart antenna radiation patterns are related to the number of elements in the array, the inter-element spacing, and amplitude distribution. | ||
