24036 为了增强唯相位波束形成(Phase-Only Beamforming, POB)的干扰和噪声抑制性能，提高非凸 POB 权值求解的实时性，该文设计了迭代优化最小化(Iterative Majorization Minimization, IMM)唯相位最小方差无失真响应波束形成器(Minimum Variance Distortion-less Response Beamformer, MVDRB)。 To improve the interference and noise suppression ability of Phase-Only Beamforming (POB) and the real-time performance to obtain the optimal weight of the uon-convex POB, a phase-only Minimum Variance Distortion-less Response Beamformer (MVDRB) via the Iterative Majorization Minimization (IMM) algorithm is designed. The distortion-less response constraint is transformed into maximizing array response in the desired direction.
24037 将无失真响应约束转化成最大化期望方向阵列响应，推导了二次型目标函数的上界，得到 IMM-POB 优化模型，并进一步推导出每次迭代的闭式最优解。 The upper bound function of the objective function in quadratic form is derived which generates the IMM-POB model. The optimal weight in closed-form for each iteration is further deduced.
24038 仿真分析表明所设计的 IMM-POB：在相同输入信噪比下，可获得高于现有迭代算法和最优 MVDRB的信干噪比改善； Simulation analysis illustrates that the proposed IMM-POB can obtain better signal to interference and noise ratio improvement compared with the existing iterative POB algorithms and the optimal MVDRB;
24039 干扰抑制性能几乎完全逼近最优 MVDRB，且具有更优的噪声抑制性； its interference suppression ability approximates the optimal MVDRB with better noise suppression ability;
24040 受快拍数影响较小； it is much less sensitive to the number of array taps compared with the optimal MVDRB;
24041 闭式最优权仅包含单次矩阵和向量乘法，使算法具有较强的实时性，可应用于大规模阵列。 it has strong real-time performance and can be applied to large-scale array.
24042 该文针对单路延迟对消系统不能有效解决多径信道的超短波无线电台共址干扰消除问题，给出了等间隔多路延迟正交合成的射频干扰对消方案，进而提出了新的衰减系数求解方法。 The one delay tap cancellation system is weakly to suppress the co-site interference between the Very High Frequency (VHF) radios in multipath channel. To overcome this obstacle, a Radio Frequency (RF) interference cancellation scheme based on the multi-tap delay and orthogonal combination is presented, as well as a new solving attenuation coefficients method.
24043 在设定时间延迟范围和参考信号路数基础上，该方法通过迭代加权实时有效估计多路参考信号的相关矩阵，接收信号与参考信号的相关向量，进而求解维纳霍夫方程得到各路衰减系数，有效抑制多径信道的自干扰，克服了已有方法需同时调节幅度和相位，以及相关向量和相关矩阵估计精度低的不足。 Considering the fixed delay scale and the number of taps, this method accurately estimates the reference signal autocorrelation matrix and the cross-correlation vector between reference signals and received signal on the basis of instantaneous and iterative weighted averaging. The attenuation coefficients are achieved by solving Wiener-Hopf equation via the estimated autocorrelation matrix and cross-correlation vector. Compared with the existing approaches, this method does not need to adjust and control the amplitudes as well as the phases of reference signals simultaneously, and it improves the accuracy of estimating cross-correlation vector and autocorrelation matrix.
24044 另外，理论分析了衰减系数的求解过程，并推导了自干扰对消比的闭合表达式。 In addition, the closed-form expression of self-interference cancellation ratio is derived through theoretically analyzing the attenuation coefficients solution.
