A high degree of intra- and inter-rater reliability was observed with the speech quality ratings across both normal and hearing impaired groups. As such, this database was used to benchmark the performance of different objective speech quality estimators in predicting the quality of frequency-compressed speech.

The purpose of this paper is to outline a model which can be used to predict the performance of HF skywave radio circuits in a nuclear environment. Despite a wealth of literature on the subject of signal absorption and attenuation, little has been discussed to date about prediction of performance levels in such an environment. The proposed prediction model for system performance is an.

High frequency (HF) is the ITU designation for the range of radio frequency electromagnetic waves (radio waves) between 3 and 30 megahertz (MHz). It is also known as the decameter band or decameter wave as its wavelengths range from one to ten decameters (ten to one hundred metres).

Frequencies immediately below HF are denoted medium frequency (MF), while the next band of higher Frequency range: 3 to 30 MHz. A technique for computing the electromagnetic compatibility of HF sky-wave communication systems is described.

Telecommunications Engineer's Reference Book maintains a balance between developments and established technology in telecommunications. This book consists of four parts. Part 1 introduces mathematical techniques that are required for the analysis of telecommunication systems.

In preparation for the second session of the High‐Frequency Broadcasting Conference the Institute for Telecommunication Sciences developed a computer program to assess the impact of planning the frequency bands allocated to the high‐frequency broadcasting service on U.S.

Factors affecting radar performance. The performance of a radar system can be judged by the following: (1) the maximum range at which it can see a target of a specified size, (2) the accuracy of its measurement of target location in range and angle, (3) its ability to distinguish one target from another, (4) its ability to detect the desired target echo when masked by large clutter echoes.

This book is both a survey of practical concepts for forecasting the performance of various telecommunication systems as well as a balanced treatment of space-weather phenomena that give rise to telecommunication impairment episodes. low frequency through extremely high frequency, which is essentially the entire real-world.
