Conference on advanced signal processing algorithms architectures and implementations XIII
作者: Huang, ZJ Ercegovac, MD Univ Calif Los Angeles Dept Comp Sci Los Angeles CA 90095 USA
We propose two-dimensional signal gating for high-performance multipliers including tree multipliers and array multipliers with an upper/lower left-to-right leapfrog (ULLRLF) structure. In ULLRLF array multipliers, th... 详细信息

4TH CONF ON advanced signal processing algorithms, architectures, AND implementations
作者: KOTA, K CAVALLARO, JR Rice Univ. (United States)
This paper describes the VLSI implementation of a CORDIC based processor element for use in a fault-reconfigurable systolic array to compute the singular value decomposition (SVD) of a matrix. The chip implements a ti... 详细信息

SPIE Conference on advanced signal processing algorithms, architectures, and implementations VIII
作者: Nelson, DJ Kenny, OP US Dept Def Ft George G Meade MD 20755 USA
In this paper, we present a new class of representations of signals in the time-frequency (TF) plane. These representations are complex valued, linear, and satisfy reconstruction conditions in which the signal and its... 详细信息

Conference on advanced signal processing algorithms, architectures, and implementations XVII
作者: Nickel, Robert M. Penn State Univ Dept Elect Engn University Pk PA 16802 USA
We are presenting a new method for super resolution tracking of frequency modulated sinusoids in white noise. The method is specifically designed to handle the rapid transient problem, i.e. the problem of tracking a c... 详细信息
