Current North American Time Division Multiple Access systems support voice services and circuit data services at a rate limited to 9.6 kb/s.
The shared channel feedback (SCF) procedures and fields as specified in IS-136 DCCH are not well-suited for long packet data transactions and do not facilitate flexible sharing of resources among u
We study a variety of problems related to scheduling and medium access control for multicast traffic in wireless networks.
System design considerations for an air-transportable ground station for satellite communication are discussed and system specification and performance figures derived.
Despite occasional experimental hints, medium-range structural order in covalently bonded amorphous semiconductors had largely escaped detection until the advent of fluctuation electron microscopy
Common carriers and their equipment suppliers continue to be faced with both the desire to meet customer needs for easily accessible and usable telecommunications services as well as the requiremen
Melting of Al was performed in a vacuum chamber with base pressure of ~1x10 sup (-8) torr, using a bank of ten 1.2 kW W lamps.
A liquid phase epitaxy system (LPE) was designed and used to grow melt oxidized Yb sub 1 Ba sub 2 Cu sub 3 O sub 7 superconducting films on SrTiO sub 3 (100) substrate.
Advances toward major technological applications of the bulk, high Tc superconductors have been hindered by two major barriers, i.e.
We report the observation of icosahedral structure in a new alloy system: Melt-spun Al(84)V(16).
