Advances in digital signal processing have helped us to realize sophisticated technologies for speech communication in cellular radio and ISDN.
We have developed epitaxial growth of active layers on a 4-inch InP-SiO2/Si substrate for datacom applications. We achieved high-quality growth of 1.55 µm AlGaInAs Multiquantum Wells.
The simple binary compound, MgB2, has created enormous excitement, due to its remarkably high T-c (39 K), its exotic electronic and phononic structure, as well as its potential technological applic
We study the transport properties of quantum point contacts in a GaN/AlGaN heterostructure.
For the scenario of either multiple (distributed) transmit antennas from a single basestation or multiple (distributed) basestations, each of which is only with a single transmit antenna, we propos
Multiple-antenna systems that operate at high rates require simple yet effective space-time transmission schemes to handle the large traffic volume in real time.
Multiple-antenna systems that operate at high rates require simple yet effective space-time transmission schemes to handle the large traffic volume in real time.
The majority of modern communication systems adopts quadrature amplitude modulation (QAM) constellations as transmission schemes.
The Karhunen-Loeve transform (KLT) is the optimal orthogonal transform for high-rate transform coding of Gaussian sources.
Describes a form of frequency divider circuit in which one of the two cross-connecting capacitors of the usual multi-vibrator circuit, is replaced by a network consisting of a circuit sharply tuned
