In this paper, we have introduced a Code Division Multiplexing transmission method which is similar to OFDM and analyze ECCM performances. We have verified CDM transmission method has a good LPI performance and a feasible ECCM performance. This capability could be useful for reduction of RF interference which occurs when many equipments operate densely in small area. The equipment that uses CDM transmission method supports variable transmission rate and order-wire effectively and conveniently to user. This CDM method has similar ECCM performance comparing to serial DS method. CDM method has good multi-path signal processing capability and could be useful for mobile communication environment.
