The use of large-scale antenna arrays has the potential to bring substantial improvements in energy efficiency and/or spectral efficiency to future wireless systems, due to the greatly improved spa

Millimeter wave (mmWave) communications are recognized as a key technology in 5G architecture by achieving highly boosted data rate due to the large bandwidth available.

The perceptual transform coding algorithm yields perceptually transparent compression at bit rates as low as 4 bits/sample, or 128kbit/sec for monophonic 32kHz sampled audio signals.

Although vector quantization (VQ) is a promising method of reducing speech coder bit rates, the degree of computation required typically makes VQ too expensive for real-time applications.

The power of side-channel leakage attacks on cryptographic implementations is evident.

Neural network models are receiving widespread attention as new computing architectures for applications such as pattern recognition and machine learning.

A survey of parallel programs written for an experimental Hypercube indicates that while systolic dataflow programs map well to a hypercube, general purpose programs with random dataflow are seriou

Reed-Solomon (RS) coders are used for error-control coding in many applications such as digital audio, digital TV, software radio, CD players, and wireless and satellite communications.

Describes the techniques used to absorb unwanted modulation products and harmonics in waveguides.

This memorandum describes a new technique to perform speech coding in which voiced frames are modeled as a sum of sinusoids that depict the harmonic structure of the original speech segment.
