Mobile communication system using various multiple access methods

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