Abstract

This paper deals with a common problem which is inherent to any FM radio communication system: the ability of two or more radios to transmit on the same RF channel at the same time, and by that to prohibit any radio from being heard. This paper proposes a sig- naling scheme which enables any radio to monitor when the RF channel is busy, and to allow the radio user to transmit only if the channel is free. The pm- ferred application of this method is usage in FM tnml- ing system, such as Motorola Smartnet system.
