The explosive growth of smart phones and other portable wireless devices such as iPad has necessitated the ubiquitous high-data-rate wireless communications more than ever. There have been extensive ongoing research and standardization efforts ongoing to meet such demand, and the operators worldwide are upgrading their wireless networks to support broadband wireless transmissions. The fourth generation (4G) wireless cellular network is one of the major efforts to fulfill such high-speed wireless communications. By employing advanced signal processing and communication techniques such as multiuser multiple-input-multiple-output (MIMO), link adaptation, relay technologies, and hybrid automatic repeat request (ARQ), the 4G system could substantially enhance the spectrum efficiency over traditional third generation wireless cellular networks.
