Recent proliferation of wireless devices had considerably increased the need for networking and provisioning intercommunication between these devices for various applications. Broadly, the wireless networks can be classified into two categories. The cellular networks and wireless local area networks can be termed as infrastructure-based wireless networks. The second category, termed as infrastructureless wireless networks include mobile ad hoc networks and sensor networks. Mobile ad hoc networks (MANETs) have use in battlefields, disaster recovery areas, intercommunication between islands or in difficult terrains, and conferencing with any infrastructure support. Sensor networks have a wide range of applications ranging from monitoring environments, sensitive installations, and remote data collection and analysis. In this tutorial we will have an in-depth view of the issues related to mobile ad hoc networks and sensor networks. The outline of our tutorial follows.Recently, in addition to adaptive signal processing (ASP), iterative signal processing (ISP) has been extensively investigated as it can significantly improve the performance of the receiver under interference-limited channel environments. One example is the turbo equalizer that can improve the performance significant by properly mitigating intersymbol interference (ISI). ISP is different from ASP in some aspects. ISP is based on off-line processing. Hence, it results in a relatively long processing delay and large memory requirement. However, as hardware and computing power have been significantly improved, the difficulties will not be obstacles to ISP becoming popular.

The main idea of the proposed tutorial is to introduce up-to-dated ISP techniques in wireless communications context. In particular, we aim to provide ISP ideas for receiver design under interference-limited channel environments. This tutorial would be a blend of theory and practice and would lie at the interface between signal processing and communications.

Note that this tutorial will be based on the book, entitled 'Adaptive and Iterative Signal Processing', that will be published by Cambridge University Press (CUP) and available by the end of 2006.

Jinho Choi (Senior Member of IEEE) was born in Seoul, Korea, in 1967. He received B.E. (magna cum laude) degree in electronics engineering in 1989 from Sogang University, Seoul, and the M.S.E. and Ph.D. degrees in electrical engineering from Korea Advanced Institute of Science and Technology (KAIST), Daejeon, in 1991 and 1994, respectively. He is now with Institute of Advanced Telecommunications (IAT), University of Wales Swansea, Swansea, United Kingdom, as a Professor (Chair in Wireless Communications). His research interests include wireless communications and array/statistical signal processing. Prof. Choi received the 1999 Best Paper Award for Signal Processing from EURASIP and a Senior Member of IEEE. Currently, he is an Editor of Journal of Communications and Networks (JCN) and an Associate Editor of IEEE Transactions on Vehicular Technology.
