| Abstract | Emerging demands for high data rate services and high spectral efficiency are the key driving forces for the continued technology evolution in wireless communications. T hird generation (3G) mobile communication systems have already been commercially deployed in certain parts of the world to meet the initial demand for high data rate packet-based serv ices including wireless internet access. Recently, several adv ancements have been introduced for 3G wireless systems to further enha nce the data rate and the system performance (e.g., high speed downlink packet access (HSDPA) in wideband code division multiple access (WCDMA) systems, 1x evolution-data and voi ce (1xEV-DV) in cdma2000 systems). Nevertheless, due to rapid growth of wireless multimedia services, it is apparent that 3G wireless systems will be unable to comply with the ever increasing demand for broadband wireless services. As a res ult, even before widespread commercial deployment of 3G wireles s systems, the standardization process of the next generatio n wireless communication systems (namely, fourth generatio n (4G) or beyond 3G (B3G) systems) has already been initiated. The n ext generation broadband wireless systems are expected to supp ort variety of services requiring different data rates and different QoS (quality of service) levels. Obviously, the key featureof 4G (or B3G) systems over growing 3G systems is the feasibility o f much higher data rate services. In this paper, an overview of leading technological advances that enable broadband wire l ss capabilities and state-of-the-art research in various asp ects of wireless communication is presented. The topics include mu ltipleinput multiple-output (MIMO) systems, cooperative diversity, ultra wideband (UWB), cross-layer design, QoS provisioning, cognitive radio and wireless security. |
