Wireless communications is emerging as the largest sectors of telecommunications industry. It is the one area that promises a lot of prospects for growth in the coming century. The major challenges for the future research and study in this field include utilizing the limited available spectrum efficiently and improved link reliability between communicating equipment. The environment in which the communication equipments are required to be operating suffers from fading and interference from other users. Frequency selective fading channels can model such hostile conditions that exist in the environment.
