Design and Implementation of WiMAX Baseband System

Design and implementation of a wireless communication system protocol stack on the hardware platform are challenging tasks, which are seldom mentioned in published results currently. In fact, the work aims at achieving the predetermined function and performance based on the specific hardware resource, which involves how to design the software architecture according to hardware, how to choice the suitable algorithms and program them optimally on programmable DSP or embedded processor, etc. Typically, there are two ultimate application modes for a communication protocol stack: dedicated ASIC or programmable DSP. However, before the protocol stack is formed into dedicated ASIC, the task of protocol or algorithms implementation and testing on the programmable DSP should be finished primarily. Therefore, the chapter will focus on the topic of development of the WiMAX PHY/MAC protocol on a multi-core DSP platform.
