On the power efficient resource allocation for the overloaded multipath CDMA systems
A comparison of the optimal power allocation for a Gaussian vector channel subject to sum power constraint under water filling principle and inverse eigenvalue problem is given. We focus on the overloaded multipath DS - CDMA systems when the channel information is known at both transmitter and receiver. We generalize the sum of power constraint for each cell by considering p-norm matrices, and we provide numerical and graphical results for an overloaded CDMA cell in the presence and the absence of the multipath fading.
