The field of digital speech processing includes the areas of speech coding, speech synthesis, and speech recognition.

We examine the benefit of digital subcarrier multiplexing in optically routed networks.

Testing of a system is an experiment in which the system is exercised and its resulting response is analyzed to ascertain whether it behaved correctly.

We describe an algorithm and a real-time hardware implementation for coding composite NTSC signals sampled at four times color subcarrier into 45 Mb/s while preserving 'Network Quality'.

The limiting noise with regard to transmitting digital data is impulsive in nature.

The Digital Transparent Processor (DTP) is an on-board application under development in Alcatel Alenia Space - Italy to accomplish increasing telecommunication's market demand for flexibility, in t

In tropospheric scatter transmission beyond the horizon, the amplitude, phase and frequency of a received sine wave exhibit random fluctuations owing to variable multipath transmission and noise.

We demonstrate digital turbulence compensation using a 12-spatial mode digital coherent receiver with a multimode pre-amplifier that provides a 6-dB sensitivity improvement.
