While integration technology has steadily improved size and performance for wireless baseband circuitry, quality factor and frequency limitations still limit RF front-end circuitry to many large di
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.
