This paper reports on experiments to estimate the speech output quality of telephone services in an instrumental way, using single-ended quality prediction models.

This paper studies the novel problem of more accurately estimating urban traffic congestions by integrating sparse probe data and traffic related information collected from social media.

The protective devices incorporated in the repeaters of transistor coaxial systems afford no protection to the cable itself.

A new method for the estimation and the compensation of IQ-imbalances in direct conversion receivers is presented.

The operate and release times of most telephone relays lie in the range from 1 to 100 millisecs. (0.001 to 0.100 sees.).

T h e selection of a relay for a circuit application, particularly so in common control systems, involves in p a r t a determination of its operating and releasing time.

Various control algorithms in wireless cellular system rely for their proper operation on signal strength measurements doen by the mobiles.

A recently proposed estimator of the offset between two clocks in a data communications network is based on an exchange of timing messages between the clocks.

Multiple-input-multiple-output (MIMO) systems can provide high data rate wireless services in a rich scattering environment.
