【Abstract】 The comparism of single code and multicode schemes transmitting in high and variable rate services in broadband CDMA system is presecanted.Theoretical analysis and mumerical computation are made,as did the simulation.The conclusion that the BER performance and system capacity of the two schemes are same under the same external condition and Rayleigh fading channel is resulted.更多还原
