Our scheme uses a weighted optimization approach to assign unequal power levels to the different subcarriers in the system, based on the received signal strength at the receiver. The optimization problem is formulated as a non-linear program, which is then solved using a gradient descent algorithm. Simulation results show that our proposed power allocation scheme outperforms traditional equal power allocation schemes, especially in scenarios with high shadowing effects.
