The number of coefficients of multi-dimensional (MD) finite-extent impulse response (FIR)
filters increases exponentially with the number of dimensions leading to significantly high …

Communications at mm-wave frequencies and above rely heavily on beamforming antenna
arrays. Typically, hundreds, if not thousands, of independent antenna channels are used to …

A low-complexity multibeam wideband transmit beamformer using a 2D sparse FIR filter
design capable of multiple beams is proposed as a digital building block for fully digital …

Recently, finger vein recognition has become integral to biometric technology that uses vein
patterns for highly secure personal recognition. Many existing studies reported accurate …

We propose a minimax design method for multi-dimensional (MD) interpolated finite-support
impulse response (IFIR) filters. As a result of the cascade structure of an MD IFIR filter, the …

We propose a weighted least-squares (WLS) design method for multi-dimensional (MD)
complex-coefficient finite-extent impulse response (FIR) filters. We consider the general form …

The optimal designs of multi-dimensional (MD) complex-coefficient finite-extent impulse
response (FIR) filters with low group delays predominantly consider only the minimization of …

Broadband beamformers designed as two-dimensional (2-D) spatially-interpolated finite-
extent impulse responses (FIR) filters, using a cascade structure, cannot employ sparse …

Antenna arrays consisting of up to thousands of elements are required in a plethora of
applications, such as wireless communications, microwave imaging, radio astronomy, and …
