Indexing terms: Maximum driving, Systolic array ABSTRACT In this work, we develop an optimized binary tree-level rule for the design of systolic array structure of Delay LMS (DLMS) adaptive filter Using our developed method higher convergence rate can be obtained without sacriJictng the properties of systolic array structure. Also, based on our optimized tree rule, user can easily design any ev...

In this paper, a novel two-element-microphone-array-based speech enhancement algorithm is proposed. This algorithm is designed to achieve better overall performance with relatively small array size. A frequency domain adaptive null-forming is used, in which adaptive noise cancelation is implemented in auditory subbands. And an OM-LSA based post ltering stage further puri es the output. The algo...

Space Time Adaptive Processing (STAP) applied on signal received from different configurations of real elements using D3LS (Direct Data Domain Least Squares). We will discuss the impact of each typical element-missing on the performance of this approach and the precision of the estimated strength of the SOI. We are interested in five different antenna configurations which are uniform linear equ...

Adaptive reconstruction of phased array MRI. Abstract-An adaptive implementation of the spatial matched filter and its application to the reconstruction of phased array MR imagery is described. Locally relevant array correlation statistics for the NMR signal and noise process are derived directly from the set of complex individual coil images, in the form of sample correlation matrices. Eigen-a...

Infinite impulse response filters have not been used extensively in active noise and vibration control applications. The problems are mainly due to the multimodal error surface and instability of adaptive IIR filters used in such applications. Considering these, in this paper a new adaptive recursive RLS-based fast-array IIR filter for active noise and vibration control applications is proposed...

This paper presents an adaptive weight computation algorithm for a robust array antenna based on the sample matrix inversion technique. The adaptive array minimizes the mean output power under the constraint that the mean square deviation between the desired and actual responses satisfies a certain magnitude bound. The Lagrange multiplier method is used to solve the constrained minimization pro...

This paper presents of Smart antenna system based on the direction of arrival (DOA) estimation and adaptive beamforming. Direction of arrival (DOA) estimation is based on the MUSIC for identify the direction of signal and adaptive beamforming is achieved by LMS algorithm. The smart antenna system designed involves a hardware part which provides real data measurement of the incident signal recei...

Frequency invariant beamforming is array processing in which the spatial response remains constant (with respect to frequency) within a wide frequency band of interest. In this paper we present a new algorithm for adaptive broadband beamforming which solves a minimum variance beamforming problem, with a structural frequency invariant beampattern constraint. This constraint allows us to reduce t...
