Pole-Zero Analysis of Distributed Radio-Frequency Acceleration Systems

Bandwidth Analysis of Multiport Radio-Frequency Systems

When multiple radio-frequency sources are connected to multiple loads through a passive multiport matching network, perfect power transfer to the loads across all frequencies is generally impossible. In this two-part paper, we provide analyses of bandwidth over which power transfer is possible. Our principal tools include broadband multiport matching upper bounds, presented herein, on the integ...

Blind identification of single-input multiple-output pole-zero systems

In this paper we present a technique for the blind identi cation of single-input multiple-output (SIMO) pole-zero (PZ) systems using only the second order statistics of the system output data. The system input is treated as an unknown deterministic sequence, and hence, restrictive i.i.d. assumptions on the input sequence are not required. We estimate the poles and zeros of the channels in two s...

Hardware acceleration of simulations of distributed systems

In recent years the study of complex systems gained prominence. Since it is usually difficult to use classical mathematic models to understand these systems, scientists and engineers have to resort to simulations. Currently programming languages like CUDA C and OpenCL are available to run large scale simulations on a GPU architecture. Alternatively simulations can be executed on agent-based sim...

Lecture 13 : Pole / Zero Diagrams and All Pass Systems

A chirp signal x(t) = e j2π ct2 2 = A(t)e jθ(t) has instantaneous frequency fx(t) = ct units of Hz (or radians, etc.) so instantaneous frequency for a linear FM chirp is a linear function of time t. The frequency is increasing linearly with time, with slope c. Note: if there are more than one simultaneous frequency components, at a particular time, then it is hard to analyze this way. But OK fo...
