Simultaneous Rate and Power Control in Multirate Multimedia CDMA Systems
Simultaneous Rate Power Control Multirate Multimedia CDMA Systems
2015/7/10
We consider a wireless multimedia CDMA system, where the different mobiles transmit at different rates. We devise a method of simultaneously optimizing the power and rate at which the different termin...
Simultaneous Routing and Resource Allocation in CDMA Wireless Data Networks
Simultaneous Routing Resource Allocation CDMA Wireless Data Networks
2015/7/10
The optimal routing of data in a wireless network depends on the link capacities, which, in turn, are determined by the allocation of transmit powers across the network. Thus, the optimal network perf...
Optimal Link Adaptation in Wideband CDMA Systems
Optimal Link Adaptation Wideband CDMA Systems
2015/7/8
We develop a general framework for optimizing link adaptation for multiuser CDMA systems in the wideband limit. The framework is then used to solve for the optimal power control policy that minimizes ...
Optimal Power Control for CDMA Systems in the Wideband Limit
Optimal Power Control CDMA Systems Wideband Limit
2015/7/8
Traditional methods for solving multiuser control problems in CDMA systems do not scale well as the number of users in the system increases. To address this problem we develop a wideband limit approxi...

码分多址 功率和速率控制 效用函数 非凸优化
2014/8/29
提出了基于效用函数的ＣＤＭＡ 网络下行链路的功率和速率联合控制最优化算法．在这类算法中，效用函数为非凸函数，经典的最优化理论很难解决这类问题．将粒子群优化方法应用于算法的非凸性设计，并通过仿真算例证明了该算法能有效解决非凸优化问题，且可保证系统的公平性．
