This section transforms the multi-objective function into a single objective function by proportion coefficients and the penalty function J(P) related to the constraints as: [Math Processing Error]F(P)=β1F1(P)+β2F2(P)+β3F3(P)+β4F4(P)+J(P) (16) where βi is the ratio coeffici...
a desired peak-to-average power ratio (PAPR) reduction for each of the one or more mobile stations for the OFDMA frame based at least in part on the estimated received signal strength; determining, by the base station, a tone reservation mode to implement at a first mobile station of the...
Methods and corresponding systems for reducing a peak-to-average signal ratio include determining peak and null samples of a symbol. Thereafter, an error signal is calculated that is responsive to the peak and null samples. In one embodiment the error signal has values corresponding to differences...
