Lossy source compression using low-density generator matrix codes: analysis and algorithms
We study the use of low-density generator matrix (LDGM) codes for lossy compression of the Bernoulli symmetric source. First, we establish rigorous upper bounds on the average dist...

An efficient variable step-size proportionate affine projection algorithm
Proportionate-type affine projection algorithms (PAPAs) are very attractive choices for echo cancellation. These algorithms combine the good features (convergence and tracking) o...
