Radio Environment Prediction for Cognitive Radio

2008 3rd International Conference on Cognitive Radio Oriented Wireless Networks and Communications (CrownCom 2008), 2008
The evaluation and the prediction of the radio environment is one of the key issues to improve the cognitive radio. The prediction accuracy of the transmission capability in each wireless media will directly affect the performance of the transmission performance.

Radio Photographs, Radio Movies, and Radio Vision

Transactions of the Society of Motion Picture Engineers, 1923
Attempts to send pictures electrically, and to see by wire, i.e., “television,” are very old, dating back well-nigh a hundred years. And as radio differs from wire only as a means of carrying the picture characteristics over the intervening distance between stations, with the advantages in favor of radio, it is quite natural that the early workers ...

Digital-to-radio converter for software radio

11th IEEE International Symposium on Personal Indoor and Mobile Radio Communications. PIMRC 2000. Proceedings (Cat. No.00TH8525), 2002
We have proposed a digital-to-radio (D/R) converter that can directly change a digital signal generated by a logic circuit into a radio signal. This D/R converter enables an RF circuit and an antenna to be composed of one simple device, and the radio can be directly controlled by software; this is the essence of software radio.

The Radio Antipodal and Radio Numbers of the Hypercube.

Ars Comb., 2011
A radio k-labeling of a connected graph G is an assignment f of non negative integers to the vertices of G such that |f(x) − f(y)| \ge k + 1 − d(x, y), for any two vertices x and y, where d(x, y) is the distance between x and y in G. The radio antipodal number is the minimum span of a radio (diam(G) − 1)-labeling of G and the radio number is the ...
