PURPOSE: To evade interference inside the same system without being influenced by signals and noise from the communication equipment of the other system. CONSTITUTION: This communication equipment for performing carrier wave detection multiple access by starting transmission after confirming that carrier waves are not detected by observing a using band is provided with a band division means 2 for dividing the band of reception signals with spread spectrum in a limited spread band width, a power detection means 3 tar detecting reception power for the respective divided bands, a control means 4 for outputting control signals by comparing the detected reception power with a reference value and a switch 6 for controlling the transmission of transmission signals by the control signals. |
