摘要

Wireless communication systems have experienced a spectacular expansion, and today provide the predominant means of accessing the Internet. The capacity of these systems is constrained by a set of scarce resources such as radio frequencies, transmit power and time slots. Information theory offers a powerful mathematical framework to understand how these transmission resources must be allocated so as to maximize the capacity at the physical layer, yielding valuable insights for the design of efficient schemes for e.g. modulation, coding and power control. Typically, however, information-theoretic models pertain to idealized scenarios: they do not account for random behavior and dynamics at higher network layers; the practical application-specific performance requirements are largely ignored; and algorithmic implementation constraints are usually not considered.
