Call for Papers for IEEE Communications Magazine Multiple Access Technologies for B3G Wireless Communications Background The B3G wireless systems promise to deliver a much higher data transmission rate and more diverse services than what current 2-3G systems can do. All-IP wireless has been emerging as the most preferred architecture for B3G wireless. Therefore, the design of future wireless air-interface has to take into account the fact that dominant load in B3G wireless channels will be high-speed burst-type traffic. The necessity to support such a great amount of burst-type traffic in wireless channels has already posed a great challenge to all existing air-link technologies based on either TDMA or CDMA. Many research initiatives have been on the way to investigate the issues on which type of multiple access technologies will be most suitable for B3G wireless. Some suggested that the current CDMA technologies (all based on DS-CDMA, such as IS-95A/B, cdma2000, UTRA, W-CDMA, TD-SCDMA, etc.) are suited only for slow-speed continuous-transmission applications such as voice, but not a good choice for high-speed burst-type traffic, as the case in future all-IP 4G wireless. Therefore, a new wave of world-wide research is imperative to search for next generation multiple access technologies, which should effectively address all the constraints and problems existing in the current TDMA and CDMA technologies, such as poor bandwidth efficiency, strictly interference-limited capacity, difficulties in performing rate-matching algorithms, complexity to implement fast adaptive equalizer, etc. The study on the next generation multiple access technologies involves many cutting-edge research topics, such as novel CDMA code design, time-frequency adaptive equalization, interference-free CDMA architecture, high data rate TDMA and innovative transceivers. The short-term objective is to look for new multiple access technologies, which could effectively enhance overall bandwidth efficiency and detection efficiency, as well as fit the all-IP wireless applications. The ultimate goal, however, is to engineer an ideal air-interface architecture whose capacity should be limited only by noise rather than interference. This issue will serve as a stimulus to accelerate technological evolution of multiple access technologies for B3G wireless applications.
