Abstract
In a microcellular system operated in the same frequency band as a cellular system, an interference-free channel is automatically searched and allocated. The microcellular system which shares the frequency band with the cellular system comprises a control unit, a base station and a multi-channel selecting receiver. The multi-channel selecting receiver monitors a use status of cellular channels of the band by repetitively scanning voice channels for a scanning time period substantially longer than the duration of any single voice communication to detect idling channels and allocates them to its own system. Whenever a communication request is issued, the base station detect a channel not used by its own system from the idling channels and allocates it for communication.
