Adaptive Array Measurements in Communications

Using easy-to-understand language and no higher than secondary school mathematics, this unique resource shows you how to predict the number of interference signals that your system can simultaneously process, the null depth that can be achieved for each interference signal processed by the system, and the effect of external influences on system performance. You learn how to make the tradeoff among various quantities such as the desirable signal level, the number of interference signals, and the possible null depth associated with each interference signal. The book is extensively referenced with over 700 equations and 55 illustrations.
