Research of Random Access MC-CDMA Performance
【摘要】 建立了综合业务模型 ,分析出单小区系统多径Rayleigh(Nakagami)的特例衰落、噪声信道下RAMC -CDMA的话音及其它实时业务的分组丢失率与用户数关系、数据业务时延与用户数关系 ,频谱利用率等性能
【Abstract】 Integrated services model is built. Performance of integrated services random access RAMC-CDMA in frequency selective MFNC is studied. Conditional probability distribution of output, packet loss probability of voice and the other real-time services, delay of data message, capacity and utilization are analyzed.Also, numerical and simulation results are presented.
