Electron plus hole tunneling is observed optically by photoluminescence in In sub (0.53) Ga sub (0.47) As/InP coupled-single quantum wells.

The edge of a two-dimensional electron system in a magnetic field consists of one-dimensional channels that arise from the confining electric field at the edge of the system(1-3).

We have fabricated tunnel junctions of the type YBa sub 2 Cu sub 3 O sub (7-delta) /barrier/Pb that show reproducible dV/dI characteristics.

We present a simple but efficientalgorithm that iteratively refines the channel estimate in a turbo equalizer exploiting soft feedback (a-posteriori likelihoods) from the decoder.

For regenerative telecom satellite systems, the turbo decoder has become a basic component of the on-board processing (OBP).

Turbo equalization iteratively detects coded data over a frequency selective channel. An 8-PSK modulation scheme gives rise to a high number of states in a trellis based equalizer.

In this contribution, we propose a new code-aided synchronization and channel estimation algorithm for uplink MC-CDMA.

In a vertical representation of a market-basket database, each item is associated with a column of values representing the transactions in which it is present.

We propose and demonstrate turbulence-resistant free-space optical communication using a 10-mode pre-amplified receiver.
