摘要: The control of transmit power has been recognized as an essential requirement in the design cellular code-division multiple-access (CDMA) systems. Indeed, allows for mobile users to share radio resources equitably and efficiently a multicell environment. Much work on CDMA systems found literature assumes quasi-static channel model, i.e., gains are assumed be constant over sufficiently long period time algorithm converge. In this paper, dynamic algorithms is considered without restriction. problem posed tradeoff between desire maximize their individual quality service need minimize interference other users. nature wireless incorporated definition. Based cost minimization framework, optimal multiuser solution derived. shown decouple, effectively converge, single-user large system asymptote, where number spreading factor both go infinity with ratio kept constant. numerical study, performance simple threshold policy near that policy. This offers support decision rules employed current
