Finding Better Precoding in Massive MIMO using Optimization Approach

  title={Finding Better Precoding in Massive MIMO using Optimization Approach},
  author={Evgeny Bobrov and Dmitry Kropotov and Sergey Troshin and Danila Zaev},
The paper studies the multi-user precoding problem as a non-convex optimization problem for wireless MIMO systems. In our work, we approximate the target Spectral Efficiency function with a novel computationally simpler function. Then, we reduce the precoding problem to an unconstrained optimization task using a special differential projection method and solve it by the Quasi-Newton L-BFGS iterative procedure to achieve gains in capacity. We are testing the proposed approach in several… Expand

Adaptive Regularized Zero-Forcing Beamforming in Massive MIMO with Multi-Antenna Users
This work proposes a special kind of regularization matrix with different regularizations for different UE, using singular values of multi-antenna users, and shows the results in comparison with other linear Precoding algorithms on simulations with the Quadriga channel model. Expand


Linear precoding via conic optimization for fixed MIMO receivers
The proposed precoder design is general, and as a special case, it solves the transmit rank-one beamforming problem and can significantly outperform existing linear precoders. Expand
Linear MMSE Multi-User MIMO Downlink Precoding for Users with Multiple Antennas
This paper considers the multi-user MIMO downlink channel, and indicates that the performance difference between the direct and duality-based method that is visible in uncoded BER curves vanishes when channel coding is introduced to the system. Expand
Optimality of zero-forcing beamforming with multiuser diversity
It is shown that a zero-forcing beamforming (ZFBF) strategy can achieve the same asymptotic sum-rate capacity as that of DPC, as the number of users goes to infinity, and an algorithm for determining which users should be active in ZFBF transmission is proposed. Expand
Near-maximum-likelihood detection of MIMO systems using MMSE-based lattice reduction
This paper adopts lattice-reduction-aided schemes to the MMSE criterion and proposes an alternative method based on an extended system model, which in conjunction with simple successive interference cancellation nearly reaches the performance of maximum-likelihood detection. Expand
Low-complexity MMSE-IRC algorithm for uplink massive MIMO systems
The proposed algorithm exploits a dimension-reduction technique to reduce the computation-intensive of the matrix inversion compared with the conventional algorithm and is shown to be equivalent to the conventional MMSE-IRC algorithm under the assumption of uncorrelated interference and noise.

Zero-forcing methods for downlink spatial multiplexing in multiuser MIMO channels
While the proposed algorithms are suboptimal, they lead to simpler transmitter and receiver structures and allow for a reasonable tradeoff between performance and complexity. Expand
Construction and capacity analysis of high-rank line-of-sight MIMO channels
The results show that even with some deviation from optimal design, the LOS MIMO case outperforms the i.i.d. Rayleigh case in terms of Shannon capacity. Expand
On the optimality of multiantenna broadcast scheduling using zero-forcing beamforming
It is shown that a zero-forcing beamforming (ZFBF) strategy, while generally suboptimal, can achieve the same asymptotic sum capacity as that of DPC, as the number of users goes to infinity. Expand

It is proved that as the number of users K grows large, the ZFDPC-SUS approach can achieve the optimal sum rate scaling of the MIMO broadcast channel, and the interesting result that the semi-orthogonality constraint imposed by SUS, whilst facilitating a very low complexity user selection procedure, asymptotically does not reduce the multi-user diversity gain in either first ( K) or second-order (K) terms.
