A mobile communication system in which various access methods may be selected according to the user's priority. In the mobile communication system, each of a mobile station and radio base stations has a radio processor, which has TDMA, CDMA and FDMA communication units. The CDMA communication unit comprises channel coders each for performing a primary modulation to a transmitting signal, spread-spectrum code generators for respectively generating different spread-spectrum signals, a clock generator/controller for controlling the generation of chip clocks to control the generation of the spread-spectrum codes, oscillators for setting different carrier frequencies to outputs calculated as products,; and a CPU for generally controlling various parts or elements to control the assignment of a CDMA signal or a TDMA signal to an arbitrary time slot transmitted from the TDMA communication unit. The radio processor transmits different signals of different access methods existing in each time slot of the same frame different signals.
