The loss of USDPA algorithm with \(R_{th}\) = 0.3 bits/s/Hz and \(P_{S} =\) 40 dBm versus time. After 1000 time slots, the user selection network can converge quickly. Therefore, the USDPA scheme converges quickly. The x-axis is the time slot, and the y-axis is the loss of the USDPA. The illustrations are the power allocation network and the user selection network
