<p>PURPOSE: To provide a radio communication system with which a communication system can be composed of simple configuration, managing efficiency is improved and safe communication is made possible even when plural master stations are adjacent. CONSTITUTION: Each master station adds '1' to the high-order 9 bits of an intra-maker specific identifier 51 inside the MAC address of the present station of 48 bits as the 10th bit and defines it as an initial shift register value 55. Therefore, the initial shift register value 55 adopts a different value for each master station. Namely, data transmitted form the respective master stations are respectively variously scrambled. At each slave station, the MAC address of the master station to be communicated is found from a burst header 61 received for each burst signal and based on this MAC address, a descramble pattern is set.</p> |
