Resource Allocation -WiMAX Systems

P. Satish Kumar, R MURALI PRASAD


Resource allocation is been shown to provide substantial performance gain in wireless systems, such as WiMAX, when full channel state information (CSI) is available. But in some fading environments (e.g., fast fading), there may not be a feedback link. In this paper, we consider resource allocation strategies for downlink multiuser mobileWiMAX systems. We address the problem of subchannel assignment and power allocation. This problem is formulated as a nonlinear stochastic constrained optimization problem. We provide an analytical solution based on the Lagrange.
