Signal processing for sensor arrays

Annals of Biomedical Engineering, 1991
Five methods have been developed to process output signals from sensor arrays to improve sensor characteristics. A multielement capacitive force sensor array with nonlinear characteristics and inter-element cross-talk was used to demonstrate and compare the performance of these methods: (1) Variable Threshold, which calculated a threshold value from a ...

Second-order neural core for bioinspired focal-plane dynamic image processing in CMOS [PDF]

, 2004
Based on studies of the mammalian retina, a bioinspired model for mixed-signal array processing has been implemented on silicon. This model mimics the way in which images are processed at the front-end of natural visual pathways, by means of programmable

Efficient minimum blind area model for system and interference uncertainty

IET Microwaves, Antennas & Propagation
In the anti‐interference of broadband communication radio, interference cancellation performance is seriously affected by the uncertainty of the working frequency selection of the communication system and the direction of hostile interference. The closed‐

Sampling Sparse Signals on the Sphere: Algorithms and Applications [PDF]

, 2015
We propose a sampling scheme that can perfectly reconstruct a collection of spikes on the sphere from samples of their lowpass-filtered observations. Central to our algorithm is a generalization of the annihilating filter method, a tool widely used in ...

Performance of Optimum Combining in a Poisson Field of Interferers and Rayleigh Fading Channels

, 2010
This paper studies the performance of antenna array processing in distributed multiple access networks without power control. The interference is represented as a Poisson point process. Desired and interfering signals are subject to both path-loss fading
