FIR filters for hardware-based real-time multi-band image blending

Creating panoramic images has become a popular feature in modern smart phones, tablets, and digital cameras. A user can create a 360 degree field-of-view photograph from only several images. Quality of the resulting image is related to the number of source ...

Phase derivative estimation from a single interferogram using a Kalman smoothing algorithm

Pramod Rastogi, Rishikesh Dilip Kulkarni

We report a technique for direct phase derivative estimation from a single recording of a complex interferogram. In this technique, the interference field is represented as an autoregressive model with spatially varying coefficients. Estimates of these coe ...

OMP with Unknown Filters for Multipath Channel Estimation

Martin Vetterli, Ivan Dokmanic

We study a modification of the orthogonal matching pursuit (OMP) for estimating sparse multipath channels. The reflectors that generate the multipath components are not ideal; rather, they act as filters, so that the returned pulses are reshaped and widene ...

Asynchronous Decoding of LDPC Codes over BEC

Amin Karbasi, Amir Hesam Salavati, Saeid Haghighatshoar

LDPC codes are typically decoded by running a synchronous message passing algorithm over the corresponding bipartite factor graph (made of variable and check nodes). More specifically, each synchronous round consists of 1) updating all variable nodes based ...

Generalized Method of Wavelet Moments for Inertial Navigation Filter Design

Jan Skaloud, Stéphane Guerrier, Yannick Stebler

The integration of observations issued from a satellite-based system (GNSS) with an inertial navigation system (INS) is usually performed through a Bayesian filter such as the extended Kalman filter (EKF). The task of designing the navigation EKF is strong ...

A 533pW NEP 31×31 pixel THz image sensor based on in-pixel demodulation

Christian Enz, Assim Boukhayma

A THz 31×31 pixel, 100 fps image sensor integrated in a 130 nm CMOS process is presented. Taking advantage of the possibility to modulate the active source that lights the scene, a significant improvement in sensitivity and NEP is achieved by shifting the ...
