Noncooperative waveform adaptation games in multiuser wireless communications

This article provided a survey of waveform adaptation algorithms for multiuser wireless communications based on noncooperative game theory. Emphasis has been given to the problem of spreading code optimization in CDMA systems, a research topic that has attracted the interest of many researchers for years, and some space has also been devoted to other applications of waveform adaptation algorithms, such as beamforming in multiantenna multiuser communications and waveform selection in cognitive radio networks. For these three research tracks we have reviewed the principal results pertaining to the issue of noncooperative waveform adaptation, and some open research problems have been discussed. We believe that, given the rapid pace at which wireless communications have been developing, waveform adaptation will play a key role in the future to enhance the performance of increasingly highly loaded wireless data networks.
