A Direct Solution for Rate Balancing in MIMO Broadcast Channels with Per-Base-Station Power Constraints
It is well-known that the main capacity limitation in cellular communication systems is due to inter-cell interference. Multi-cell signal processing, for example joint transmission from multiple base stations to multiple terminals, is known to strongly improve spectral efficiency and system fairness by actively exploiting interference rather than treating it as noise. Specifically, we consider ...
متن کاملConstrained power allocation schemes for coordinated base station transmission using block diagonalization
In this study, we propose several power allocation schemes in a coordinated base station downlink transmission with per antenna and per base station power constraints. Block Diagonalization is employed to remove interference among users. For each set of power constraints, two schemes based on the waterfilling distribution are proposed and compared to the optimal solution, which can only be obta...
متن کاملImproved Linear Precoding over Block Diagonalization in Multi-cell Cooperative Networks
In downlink multiuser multiple-input multiple-output (MIMO) systems, block diagonalization (BD) is a practical linear precoding scheme which achieves the same degrees of freedom (DoF) as the optimal linear/nonlinear precoding schemes. However, its sum-rate performance is rather poor in the practical SNR regime due to the transmit power boost problem. In this paper, we propose an improved linear...
متن کاملDesign of MIMO-OFDM multi-hop relaying with cooperative base station
Basically, in cellular network systems, the relay station (RS) is used to increase the cell coverage of mobile stations (MS) at a cell edge. But, the system performance due to the use of RS is interfered by the neighboring cells and decreased by the low power of received signals, generally. In order to overcome these disadvantages and get a diversity gain or a high data rate, we design and prop...
متن کاملBase Station Association Game in Multi-cell Wireless Networks
We consider a multi-cell wireless network with a large number of users. Each user selfishly chooses the Base Station (BS) that gives it the best throughput (utility), and each BS allocates its resource by some simple scheduling policy. First we consider two cases: (1) BS allocates the same time to its users; (2) BS allocates the same throughput to its users. It turns out that, combined with use...
