OFDMA for Broadband Wireless Access 

by Slawomir Pietrzyk, IS-Wireless

Here's the first book to address the critical problems of radio resource management (RRM) and quality of service (QoS) for OFDMA systems, including possible solutions presented as RRM algorithms. Discussing OFDMA radio resource management in the context of broadband wireless access systems such as WiMAX, this unique resource serves as an excellent reference for your OFDMA system design work and provides expert guidance on emerging enhancements to WiMAX technology. You learn how to use the algorithms presented in the book to create new features and functionalities to help differentiate your product in the marketplace. 

You discover highly effective methods for the management of available resources, such as RF bandwidth and transmit power, which in turn leads to higher data rates, greater capacity, and the ability to operate under lower resource consumption. Moreover, the book helps you make a shift from random RF bandwidth allocations to deterministic allocations, efficiently reuse available spectrum, and better understand the interference scenario.
