Abstract :
Relevant to the uplink of a VSG-CDMA system, a technique part of 3G standards, this work seeks power and data rate allocation for each of the N terminals, so that the network weighted throughput is maximized. The weights admit various interpretations, including levels of importance, "utility", and price. We have learned that at least one terminal should operate at the highest available data rate. Our analysis leads to allocations in which terminals not operating at the highest data rate operate at the same signal-to-interference ratio (SIR). This value is determined by the physical layer through the function that gives, in terms of the received SIR, the probability that a data packet is received correctly. Other factors held constant, lowering the highest available data rate increases the number of terminals which should operate at maximum data rate. This analysis conforms to classical optimization theory. Our model should accommodate a wide variety of physical layer.
