The increasing demand for portable and mobile communication devices has made wireless communication an indispensable field of research. The performance of any wireless communication system is determined to a large extent by the characteristics of the channel. For the purpose of system design and development, it is advantageous to have knowledge of the characteristics of the channel. In this paper, we discuss the various channel models that are in use today. We also present an overview of the various estimation and equalization algorithms that are widely employed. We then present the results of the simulations of the various channel models, and the observations made from these simulations. Finally, we describe the theory of constant power water filling algorithm and how it can applied to maximize the capacity of a Rayleigh fading channel. © 2010 IEEE.
