N the design of a sound transmission system to be correlated with a visual system, the requirements as to perfection of results desired are no more stringent than for other high grade sound repprod

The sound velocity and attenuation near 10 MHz have been measured on a sintered sample of La sub 2.85 Sr sub .15 cuO sub 4.

MARSIS (Mars Advanced Radar for Subsurface and Ionosphere Sounding) is a low frequency nadir looking sounding radar selected by ESA as a payload of the Mars Express mission, whose primary Scientifi

In the 3rd generation partnership project (3GPP) long term evolution (LTE) time division duplex (TDD) systems, base stations use uplink sounding reference signals (SRSs) to estimate downlink channe

In the long-term evolution (LTE) time division duplex (TDD) systems, base stations (BSs) use uplink sounding reference signals (SRSs) to estimate downlink channel state information (CSI) for downli

We study a lossy source-broadcasting problem involving the transmission of a binary source over a two-receiver erasure broadcast channel.

1.1 Informal statement of the problem To fix ideas, let us consider the following problem.
