Abstract :
In this paper, a fully distributed power control algorithm (PCA) based on the minimum mean squared error (MMSE) receiver is introduced. We study the performance of a synchronous MMSE based DS-CDMA system in which the proposed PCA is implemented. The receiver filter coefficients are obtained using the Wiener solution or an adaptive algorithm. We also study the convergence of the SINR and the total transmitted power and we compare, in terms of the capacity, the performance of a system in which the proposed power control has been implemented with a system without power control
