This letter describes a new parallel combinatorial delayed multiplexing CDMA system for high-bit-rates mobile communications. It combines delayed multiplexing and parallel combinatory methods with the CDMA system to provide higher bit rates without the use of complex receivers. The results of computer simulations using the double-spike Rayleigh fading channel model in a multiple-user environment show that its down-link BER performance is the same as that of the conventional multicode system.
