The existing ADSL standard allows for two possible transmission systems: frequency division duplexing (FDD) and echo cancelling (EC).
This paper presents an analysis of the recursive systematic double-binary convolutional codes (RSDBC) and a performance criterion which can be used to establish their hierarchy.
A new area-distributed surface-mount technology has been developed that is suitable for the solder assembly of VLSI pad grid array packages onto printed circuit boards.
Current leakage in Channeled Substrate Buried Heterostructure (CSBH) lasers with semi-insulating InP:Fe layers grown by metallo- organic chemical vapor deposition (MOCVD) reduces the power output o
Double-pulse injection seeding is used to modify the spectral emission of a terahertz quantum cascade laser (THz QCL).
There is a need for echo cancelers for echo paths with long impulse responses (greater than or equal to 64 ms).
Optical transmission employing doubly periodic dispersion maps at 10 and 40 Gbit/s data rates is reported.
We consider networks of processors where each processor either has one inlink and one outlink, or two inlinks and two outlinks.
The capacity of wireless downlink communication to mobile receivers in a dense urban environment is limited primarily by co-channel interference.
In this paper system level simulation results from the performance evaluation of applicable downlink beamforming concepts for UMTS are presented.
