Iterative transmitter and receiver optimization for synchronous CDMA systems
Şennur Ulukuş, Aylin Yener · 2003
The user capacity and the information theoretic sum capacity of a single-cell CDMA system have been recently shown to be achieved by the same transmit strategies. We propose an alternating minimization based algorithm that updates the transmitters and the receivers of the users iteratively. The algorithm is suitable for online implementation and alleviates the need for scheduling of the user updates, both of which are in contrast with the previously proposed algorithms.
