Description: Squaring circuits are an important building block for impulse-radio UWB non-coherent receivers. This work proposes a squarer, based on the quadratic law of saturated transistors. Such a circuit has already been proposed for lower frequency applications, therefore this work focuses on the extension to ultra wide bandwidth, with particular care to the consequences related to the deviation from the ideal quadratic law of 0.18μm CMOS transistors.

Description: 本文提出一种新的相干波束形成方法，利用内插变换对相干背景下的真实阵列进行虚拟平移，得到多个虚拟平移后的信号协方差矩阵；对其进行平均后，所得到的相干信号协方差矩阵具有满秩性。利用一般的波束形成法求出最优权向量。该方法解决了五阵元均匀圆阵下二维相干信号的波束形成问题。-This paper presents a new coherent beamforming methods, the use of interpolation transform the context of coherent arrays of virtual real translation, from a number of virtual post-translational signal covariance matrix their average after by Coherent signal covariance matrix has full rank of. Beamforming using the general method to derive the optimal weight vector. The method to solve a five-element uniform circular array of two-dimensional signals coherent beamforming problem.
