By means of the radio signaling system described it is possible, through the addition of a comparatively simple attachment to a standard radio telephone transmitter, to modulate the carrier with an
TN transmitting speech over radio telephone circuits there are a number of conventional methods of increasing the signal with respect to the noise.

Starting from the general requirements imposed on the transmitting medium, this paper discusses the engineering of a radio system for television purposes and describes the radio facilities actually
We present a novel technique for radio transmitter identification based on frequency domain characteristics.
Diffusion theory is found to provide a simple yet accurate expression for the average received radio power loss indoors in non-Line-of-Sight. Effective specific absorption is the sole parameter.
Diffusion theory is found to provide a simple yet accurate expression for the average received radio power loss indoors in non-line-of-sight propagation.
Many digital radio-relay routes use radio-frequency channel arrangements originally designed to accommodate analog radio-relay systems.
