Given a matrix A, it is often desirable to find a good approximation to A that has low rank. We introduce a simple technique for accelerating the computation of such approximation...

We consider a first-order Markov source, which is predictively encoded using a DPCM-style encoder. The quantized compressed prediction residual is transmitted over an erasure chan...

Abstract—In this paper, we investigate the effect of quantization noise and roundoff errors involved in finite-precision (FP) signal processing on the performance of multiple-in...
