Spreading and Power Allocation for Multiple Antenna Transmission using Decorrelating receivers
We propose a new scheme for multiple antenna transmission in the context of spread spectrum signaling. The new scheme consists of using shifted Gold sequences to modulate independent information on the multiple antennas. ...
Programmable Stream Processors
Stream processing promises to bridge the gap between inflexible special-purpose solutions and current programmable architectures that cannot meet the computational demands of media-processing applications.
The Equivalent Circuit Concept: The Current-Source Equivalent
The equivalent circuit concept derives from the Superposition Principle and Ohm's Law. Two forms of the equivalent circuit, the Thevenin equivalent and the Norton equivalent, distill any linear circuit into a source and ...
On Beamforming with Finite Rate Feedback in Multiple Antenna Systems
In this paper, we study a multiple antenna system where the transmitter is equipped with quantized information about instantaneous channel realizations. Assuming that the transmitter uses the quantized information for ...
A Rapid Prototyping Environment for Wireless Communication Embedded Systems
(Hindawi Publishing Corporation, 2003-05-01)
This paper introduces a rapid prototyping methodology which overcomes important barriers in the design and implementation of digital signal processing (DSP) algorithms and systems on embedded hardware platforms, such as ...
Nonlinear Wavelet Transforms for Image Coding via Lifting
We investigate central issues such as invertibility, stability, synchronization, and frequency characteristics for nonlinear wavelet transforms built using the lifting framework. The nonlinearity comes from adaptively ...
Optimal Sampling Strategies for Multiscale Models with Application to Network Traffic Estimation
This paper considers the problem of determining which set of 2<sup><i>p</i></sup> leaf nodes on a binary multiscale tree model of depth N (<i>N</i>><i>p</i>) gives the best linear minimum mean-squared estimator of the ...
