53378 算法利用 p-范数来代替 2-范数对误差不确定性进行总体修正,从而解决导向矢量和样本方差矩阵同时存在失配误差时所导致的波束形成器性能下降问题。 By using the p-norm to replace 2-norm, the algorithm modifies the error uncertainty to resolve the beamformer perfomance descending as the concurrent mismatch errors on steering vectors and swatch variance matrix.

53380 仿真结果验证了在不同实验条件下,相比于传统的对角加载算法,使用最优 p 范数比 2-范数约束具有更好的性能。 Simulation results validate the better restriction performance using the optimization p-norm than the 2-norm under the different conditions, comparing with the conventional diagonal loading algorithms.
53381 为解决阵列勘探在现场铺设时,采集节点地址容易发生错乱的问题,提出了一种 “流水线逐级增长”与“双次对比”相结合的动态分配方法,以实现在任何现场铺设条件下均能有序地设置所有采集节点的地址。 Address of collection node is confused easily when array exploration system is connected in the field. For this problem, a dynamic address allocation algorithm of “gradual growth based on pipeline” and “double contrast” is proposed to set address of collection nodes sequentially in array exploration system.
53382 基于阵列勘探的结构特点,使各个采集节点的地址以流水线的方式在同一时间内同时增加,从而实现采集节点地址的并行快速设置,缩短系统初始化的时间。 Based on the structural features of array explorationsystem, address of each collection node grows at the same time to achieve quickly the set of address of nodes, which reduces the system initialization time.
53383 同时采用对每个采集节点的地址进行两次对比设置的方法,提高节点地址被正确设置的可靠性。 At the same time, security of address of nodes being set correctly is improved through the method of comparing the address of nodes in twice address allocation.
53384 搭建了具有 8 个采集节点的实验系统,结果表明 8 个节点地址设置总时间为 162. 55s,与理论分析一致,同时也证明了该方法的有效性。 An experimental system with eight collection nodes is established, and experimental results show that the set total time of address of eight nodes is 162. 55s, which is consistent with the theoretical analysis and demonstrate the effectiveness of the address allocation algorithm.
53385 本文提出了适用于医学领域的 R-MOSFET-C 滤波器,采用 MOSFET 代替传统 RC 有源滤波器中的电阻,实现可调、超低截止频率。 A low-pass R-MOSFET-C filter with a tunable cutoff frequency is proposed in the paper. In the filter, a MOSFET is employed to replace the resistor in a typical topology of the RC active filter to achieve the tunable and ultra-low cutoff frequency, which is suitable for medical applications.
53386 该滤波器采用 UMC 0. 13m CMOS 工艺,电源电压为 1. 2V。 The filter is implemented in UMC 0. 13um CMOS technology with a 1. 2V supply voltage.
