Abstract :
We consider the problem of transmitter optimization to maximize the downlink sum rate of a multiple antenna cellular system with perfect data cooperation between the base stations and a separate power constraint per base station. To perform this non-convex downlink transmitter optimization we investigate incremental power allocation strategies combined with BC-MAC duality results.
