Abstract :
This paper considers power control for log-normal fading channels. We adopt a stochastic optimal control framework. Under a bounded control constraint, the stochastic control is analyzed by the viscosity solution approach. When a quadratic type cost index is used without a bound constraint on the control, the value function is a classical solution to the degenerate HJB equation and the feedback control is affine linear.
