Abstract. An iterative method LSMR is presented for solving linear systems Ax = b and leastsquares problem min Ax - b 2, with A being sparse or a fast linear operator. LSMR is base...
For general memoryless systems, the typical information theoretic solution - when exists - has a "single-letter" form. This reflects the fact that optimum performance ca...
This paper studies the performance of hybrid-ARQ (automatic repeat request) in Rayleigh blockfading channels. The long-term average transmitted rate is analyzed in a fast-fading s...
The Dynamic Host Configuration Protocol (DHCP) is a widely used communication protocol. In this paper, a portion of the protocol is chosen for modeling and verification, namely th...
—The general Gaussian multiple-access wiretap channel (GGMAC-WT) and the Gaussian two-way wiretap channel (GTW-WT) are considered. In the GGMAC-WT, multiple users communicate wit...
