THE INCREASING needs of government, business, and industry have, with emphasis, pointed to the need for an advanced concept in communications. Radio and carrier spectra are at a premium. These facts, together with the knowledge that considerable improvement could be realized in system performance, provided the motivation which, in the past 8 years at Collins Radio Company1 has resulted in the development of predicted wave signalling (PWS). PWS employs kinematic filtering and is most often used with multichannel or multiplex systems, and it has been named “Kineplex.”
