Description: 传统的幅度约束波束形成器是一个非凸问题，需将原始模型化为线性规划进行间接求解。该文针对均匀线阵提出一种相位响应固定幅度响应约束(PFMC)的稳健波束形成方法。利用权矢量逆序列对应的传递函数与阵列响
应函数只差一个相位因子这一性质，将阵列响应的相位设置为固定的线性相位，仅对阵列响应的实数幅度进行约束，从而得到一个凸的代价函数，最优权矢量可以利用内点法求出。-The conventional magnitude constraints beamformer is a non-convex issue which is reformulated as a
linear programming issue. A robust beamformer with Phase response Fixed and Magnitude response Constraint
(PFMC) is proposed for Uniform Linear Array (ULA). Making use of the property that there is only a phase factor
difference between the transfer function of the inverse sequence of the weight vector and the array response
function, the phase response is set to be linear and the real magnitude response is constrained. Thus, a convex
optimization cost function is established whose optimal solution can be found out by highly efficient interior point
method. Platform: |

Description: We present a novel beamforming technique
for multi-user frequency-selective indoor channels called
interference-nulling time-reversal (INTR). The beamformer is
implemented with a pre-filter designed to minimize the interuser
interference present in conventional time-reversal (TR).
Moreover, our technique relies on a large number of antennas at
the transmitter to mitigate inter-symbol interference, enabling
low computational complexity receivers. We demonstrate that
INTR outperforms previous TR techniques with respect to
average bit error rate per user and achievable sum rate. Thus,
INTR can be used for space division multiple access in no-Iine-ofsight
mm-wave massive MIMO, providing remarkable diversity
and multiplexing gains. Platform: |
