The great success of the Internet and wireless communications has opened a new vista for future all-IP wireless applications, driven by increasing demand for packet data services in worldwide third-Generation (3G) and 3.5G networks. It has been envisioned that the future wireless systems will operate based mainly on burst data services carrying multimedia contents, including voice, data, image, and video. The need to support high-speed burst-type traffic in wireless channels has already posed a great challenge to the current air link technologies based on Code-Division Multiple Access (CDMA). There has been a great deal of debate on the air link technologies most suitable for 4G wireless.
