This article reviews recent work on electron transport in graded gap semiconductors.
A new technique is proposed for constructing trellis codes, which provides an alternative to Ungerboeck's method of "set partitioning".
Describes the design of a sectionalized transmitting equipment in which the process of switching to new frequencies is much simplified and which is so devised that sections for other frequencies ma
We consider the problem of receiver design of wideband multiple transmitter/multiple receiver (MTMR) antenna systems (also known as BLAST systems).
We derive new asymptotic upper bounds on the generalized weights of a binary linear code of a given size. We also prove some asymptotic results on the distance distribution of binary codes.
In the new system the speed of signalling remains at 70 bauds per channel, the carrier frequencies are spaced more closely together and are odd harmonics of 60 p.p.s. instead of 85 p.p.s.
After a brief presentation of the context of the French transport network, a new cell-based photonic network architecture is presented.
We demonstrate single-carrier 518-Gb/s transceiver designed for 6600 km, single-carrier 420- Gb/s transceiver designed for 13200 km, and dual-carrier 1 Tb/s transceiver designed for 4000 km, lev
The performances of electroabsorption (EA) modulators integrated with a DFB laser (EA-DFB) are limited by optical feedback and chirp characteristics.
This paper discusses the utilization of an original topology of dielectric resonator acting on whispering gallery modes for the design of filters for telecommunication systems applications.
