    • PURPOSE: An apparatus and method for radio communication are provided to decide the channel capacity of the radio channel in consideration of false alarm probability. CONSTITUTION: The channel capacity decision unit(110) decides the channel capacity of the radio channel in consideration of the false alarm probability. The determining parameter(120) decides the probability value for maximizing the channel capacity. The sensor(130) senses the radio channel based on in the probability value and the detection-length value. The system environment information collecting part collects the system environment information of the level user system about the priority user system about the radio channel and radio channel. The channel capacity decision unit decides the channel capacity.
