Measuring and Regulating Electromagnetic Phase in Communication Systems
نویسنده
چکیده
Electromagnetic phase measurement is a key measurement technology in optical communication as well as in microwave photonics. The present lecture re-examines recent progress in electromagnetic phase control and its relevance to future communication systems. Electromagnetic phase measurement and regulation techniques are presented while tracing a path through a communication system from transmitter (such as a frequency-stabilised laser) via transmission medium to an electromagnetic detector. An understanding of phase noise at each step in the path and how it may affect frequency standards in optical and rf telecommunication systems is essential.

متن کاملOn the Practical Aspects of Joint Passive Phase Conjugation and Equalization Underwater Communication Systems
Underwater acoustic communication systems suffer from the channel impairments which results in time spreading of the transmitted signal. In underwater environment, multiple replicas of the transmitted signal are received at the receiver through different paths, which causes significant Inter-Symbol Interference (ISI). Decision Feedback Equalizers (DFE) was utilized to overcome this type of inte...

Modern microwave and millimeter wave phased array antennas are attractive because of their ability to steer wave beams in space without physically moving the antenna element. A typical phased array antenna may have several thousand elements fed by a phase shifter for every antenna, which can steer the resulting array beam to different directions. Their low loss, low cost and lightweight phase s...
