ABSTRACT
Adaptive signal processing plays a pivotal role in the emerging next-generation wireless networks. The IEEE 802.16 standard-basedworldwide interoperability formicrowave access (WiMAX) system has deployed various adaptive processing techniques both at the physical (PHY) and the Medium Access Control (MAC)-layer. In this chapter, we discuss the role of adaptations at the various layers
in theWiMAX protocol stack, in enhancing resource utilizations and system performance.We take a close look at theWiMAXwireless network standards and discuss key enhancements provided by the use of adaptation techniques specified in the standard. Current protocols and algorithms employed in the system are reviewed, and future research and deployment trends are also discussed.
