Convex Approximated Weighted Sum-Rate Maximization for Multicell Multiuser OFDM
This letter considers the weighted sum-rate maximization (WSRMax) problem in downlink multicell multiuser orthogonal frequency-division multiplexing system. The WSRMax problem under per base station transmit power constraint is known to be NP-hard, and the optimal solution is computationally very expensive. We propose two lesscomplex suboptimal convex approximated solutions which are based on s...
متن کاملAn efficient algorithm for weighted sum-rate maximization in multicell downlink beamforming
This paper considers coordinated linear precoding for rate optimization in downlink multicell, multiuser orthogonal frequencydivision multiple access networks. We focus on two different design criteria. In the first, the weighted sum-rate is maximized under transmit power constraints per base station. In the second, we minimize the total transmit power satisfying the signal-to-interference-plus...

متن کاملImproved and weighted sum rate maximization for successive zero-forcing in multiuser MIMO systems
We propose an improved algorithm for optimizing the transmit covariance matrices for successive zero-forcing (SZF) precoding in multiple-input multiple-output systems. We use a conjugate gradient projection method to solve the optimization problem. Our algorithm improves upon the existing method twofold. First, the existing covariance optimization method, with higher SNRs or more simultaneously...
متن کاملWeighted Sum Rate Maximization for MIMO-OFDM Systems with Linear and Dirty Paper Precoding
Many sophisticated resource allocation strategies are based on the maximization of the weighted sum of data rates for a given transmit power. While this problem can be easily solved for orthogonal multiple access schemes like TDMA, it is much more complicated if users are separated in space using multiple antennas at the base station due to the mutual coupling. In this paper, we propose a new p...
