A Divergence Minimization Approach to Joint Multiuser Decoding for Coded CDMA
In this paper, a theoretical framework of divergence minimization (DM) is applied to derive iterative receiver algorithms for coded CDMA systems. The DM receiver obtained performs ...

Efficient hardware code generation for FPGAs
r acceptance of FPGAs as a computing device requires a higher level of programming abstraction. ROCCC is an optimizing C to HDL compiler. We describe the code generation approach i...

Improved audio coding using a psychoacoustic model based on a cochlear filter bank
Perceptual audio coders use an estimated masked threshold for the determination of the maximum permissible just-inaudible noise level introduced by quantization. This estimate is d...

Transform-domain temporal prediction in video coding: Exploiting correlation variation across coefficients
Temporal prediction in standard video coding is performed in the spatial domain, where each pixel is predicted from a motioncompensated reconstructed pixel in a prior frame. This ...

Feedback Capacity of Stationary Gaussian Channels
Abstract-- The feedback capacity of additive stationary Gaussian noise channels is characterized as the solution to a variational problem. Toward this end, it is proved that the op...
