Abstract: In this paper, a joint linear pre-coder and combiner optimization scheme is proposed to reduce the multi- user interference in the distributed antenna system (DAS). The pre-coder is designed based on the modified weighted signal-to-caused interference ratio (SCIR) which considers the interference on others caused by the desired user and the users channel condition. And the combiner is chosen based on the signal-to- interference-plus-noise ratio (SINR) which considers the interference on the desired user caused by others. The average user rate and symbol error rate (SER) are investigated through Monte Carlo simulation. The simulation results show that the proposed scheme outperforms other schemes.

Zero-forcing methods for downlink spatial multiplexing in multiuser MIMO channels
TL;DR: While the proposed algorithms are suboptimal, they lead to simpler transmitter and receiver structures and allow for a reasonable tradeoff between performance and complexity.
Pilot Contamination and Precoding in Multi-Cell TDD Systems
TL;DR: The paper shows that the precoding matrix used by the base station in one cell becomes corrupted by the channel between that base station and the users in other cells in an undesirable manner and develops a new multi-cell MMSE-based precoding method that mitigates this problem.

TL;DR: The optimality and global convergence of the algorithm is proven and stopping criteria are given, and the global optimum of the downlink beamforming problem is equivalently obtained from solving a dual uplink problem, which has an easier-to-handle analytical structure.

Pilot Contamination and Precoding in Multi-Cell TDD Systems
TL;DR: In this paper, a multi-cell multiple antenna system with precoding used at the base stations for downlink transmission is considered, where the precoding matrix used by the base station in one cell becomes corrupted by the channel between that base station and the users in other cells in an undesirable manner.

TL;DR: In this paper, throughput performance analysis of the chunk-based subcarrier allocation is presented by considering the average bit-error-rate (BER) constraint over a chunk in downlink multiuser orthogonal frequency division multiplexing (OFDM) transmission.
