"Next Generation CDMA vs. OFDMA for 4G Wireless Applications"

IEEE Wireless Communications Magazine
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 2.5G and 3G networks. It has been envisioned that the future wireless systems will be operating based mainly on burst data services carrying multimedia contents, including voice, data, image and video. The needs to support high-speed burst-type traffic in wireless channels have already posed a great challenge to the current air-link technologies based on CDMA. There have been a lot of debates on the air-link technologies most suitable for the 4G wireless. It has been suggested from the research that the traditional CDMA technologies (used in IS-95, CDMA2000, W-CDMA, TD-SCDMA, etc.) are suited only for slow-speed continuous-transmission applications such as voice, but not suitable for high-speed all-IP wireless. Therefore, some new multiple access technology, such as orthogonal frequency division multiple access (OFDMA), has been proposed to replace CDMA as a prime air-link design for 4G wireless. However, the OFDMA also suffers its own technical limitations, such as sensitivity to peak-to-average-power-ratio (PAPR), nonlinear channels and so forth, which will be the detrimental factors to its successful applications in 4G wireless. On the other hand, CDMA technology with its many unique features still has a great potential for further technological evolution. In this special issue, various important issues pertaining to next generation CDMA and OFDMA technologies will be addressed and compared. The objective of this special issue is to accelerate technological evolution of air-link architecture for 4G wireless communications.

Subjects

The papers in this Special Issue will focus on state-of-the-art research in various physical-layer aspects of next generation CDMA and OFDMA technologies for 4G wireless. We solicit papers covering a variety of topics that include (the submissions irrelevant to 4G wireless will not be considered): Articles should be tutorial in nature and should be written in a style comprehensible to readers outside the specialty of the article. However, papers presenting original contributions will also be considered, as long as the presentation is accessible and the paper length is kept within the appropriate limits. Articles should not exceed 4500 words. Figures and tables should be limited to a combined total of six. For manuscript submission, authors should follow the IEEE Wireless Communications Magazine manuscript format described in the "Information for Authors" at http://www.comsoc.org/pubs/pcm/sub_guidelines.html. Prospective authors should submit the all-in-one PDF version of their complete manuscripts (which should be compressed if the file size exceeds 1 MB) via email to the lead Guest Editor (Hsiao-Hwa Chen) by October 1, 2006. The important dates for this special issue are given as follows:
