Recent advancements in wireless technology have resulted in an unprecedented demand for spectral resources. To make efficient use of available spectrum, it is necessary to reuse bandwidth over relatively small geographic areas. However, increasing frequency reuse also increases interference, which decreases system capacity and/or service quality. Modeling, prediction, and control of interference therefore plays a central role in the design of a wireless communications system. The title of this special issue, `Interference in Mobile Wireless Systems', covers a broad range of topics. The 15 papers in this issue can roughly be divided into three categories: (i) sources and modeling of interference, (ii) the effect of interference models on performance and system capacity, and (iii) interference suppression and multiuser detection. There is, of course, overlap among these topics. The papers are written by 29 authors in nine different countries (6 papers from Europe, 5 from North America, 3 from Australia and New Zealand, and one from Asia). It is interesting to note that 12 out of 15 of the papers in this special issue are concerned with Direct-Sequence Code-Division Multiple Access systems.
