Sensitivity of soft-decoded PM-8QAM was improved by 1.1-dB by moving to a new 64 point 4D constellation and to a tailored LDPC code.
In this experimental investigation two novel heat sink designs that employ different flow phenomena for enhanced heat transfer are presented.
We motivate the description of heavy-electron metals in terms of concepts from the Kondo problem. These concepts are used to discuss magnetism and superconductivity in heavy-electron systems.
Quantum noise reduction to levels nearly 1 dB below the standard quantum limit are reported for light frequencies near an atomic Na resonance.
First experimental results have been obtained on strong magnetic X-ray dichroism in the M(4,5) absorption spectra of magnetically ordered rare earth materials, in accordance with recent prediction
Pulse-code modulation system is described which provides 24 channels, with 8 kc/s sampling, 70 quantization steps and amplitude compression.
We experimentally characterize implementation penalties due to a limited effective number of bits (ENOB) of the analog-to-digital converter (ADC) for Nyquist shaped 16-, 64-, and 256-ary quadrature

An N-channel DOES (Double heterostructure Opto-Electronic Switch) has been demonstrated as in the case of the p-channel device, there is a high impedance state without light emission and a low impe
Multimoding is n impairment caused by mode conversions and multiple reflections in the horn antenna and the circular waveguide system.
