Chapter 11Link-Level Performance of WiMAX

The goal of any communication system is to reliably deliver information bits from the transmitter to the receiver, using a given amount of spectrum and power. Since both spectrum and power are precious resources in a wireless network, it should come as no surprise that efficiency is determined by the maximum rate at which information can be delivered using the least amount of spectrum and power. Since each information bit must reach the intended receiver with a certain amount of energy—over the noise level—a network’s power efficiency and bandwidth efficiency cannot be maximized at the same time; there must be a trade-off between them. Thus, based on the nature of the intended application, each wireless ...
