MVDR ALGORITHM BASED LINEAR ANTENNA ARRAY PERFORMANCE ASSESSMENT FOR ADAPTIVE BEAMFORMING APPLICATION [PDF]

Journal of Engineering Science and Technology, 2017
The performance of Minimum Variance Distortionless Response (MVDR) beamformer is sensitive to errors such as the steering vector errors, the finite snapshots, and unsatisfactory null-forming level. In this paper, a combination of MVDR with linear antenna

Noise to Signal

, 2023
With the introduction of information theory in the middle of the 20th century, the concept of noise came to be contrasted with signal. The exhibition Noise to Signal mainly consists of two projects that highlight the relative nature of these terms.

Joint transceiver beamforming in MIMO cognitive radio network

Tongxin xuebao, 2015
An iterative SDP-MMSE algorithm based on semidefinite programs (SDP) and minimum mean squared error (MMSE) was introduced to minimize the total transmit power. And a further approach on the max-min fairness beam-forming was presented.

MIMO radar array design based on unequal subarrays

四川大学学报. 自然科学版, 2017
The idea of dividing the transmitting array of MIMO radar into unequal subarrays was proposed in the paper. This kind of MIMO radar obtains the coherent processing gain and the waveform diversity gain which the MIMO radar with equal subarrays (called it ...

A PPN-Based Improved QAM-FBMC System With Jointly Optimized Mismatched Prototype Filters

IEEE Access
Recently, it is shown that a spectrally-efficient low-complexity quadrature amplitude modulation (QAM) filter-bank multicarrier (FBMC) system can be designed by relaxing the constraints on the time-frequency (TF) product at the transmitter (TX) and the ...

Semiparametric inference in correlated long memory signal plus noise models [PDF]

This paper proposes an extension of the log periodogram regression in perturbed long memory series that accounts for the added noise, also allowing for correlation between signal and noise, which represents a common situation in many economic and ...
