We review the basics of all-optical signal regeneration with an emphasis on reshaping.

We review recent results on the regeneration of phase encoded (BPSK, QPSK) signals and discuss paths towards regeneration of amplitude/phase encoded (QAM) signals.

This paper proposes a positioning method for the GPS receiver used in fuse with single antenna as compared to the traditional multi-antenna mode.

The overall quality of the communication link...is completely related to the ratio of the signal power at the receiver to the noise (or interference and noise as the case may be) power, called the

We measure the propagation of a signal power transient and the associated gain transient in a broadband all Raman amplified system over ultra-long haul distances.

Spatial filtering with microphone arrays is a technique that can be utilized to obtain the signal of a target sound source from a specific direction.

The word detection suggests a decision between just two alternatives: either a signal was transmitted, or it was not.

The single-frequency signaling system for long-distance telephone trunks frees dial calls from the range and other limitations imposed by d-c signaling methods.

Dynamic power control in cellular systems has been long practiced and widely proposed for interface reduction, dynamic range control, and terminal battery savings.

The Pontryagin maximum principle may be considered to be a generalization of methods of calculus of variations that permits solution of optimization problems with inequality contraints.
