第三代移动通信无线传输技术算法结构及其COSSAP中的仿真

The Algorithm Architecture of Radio Transmission Technology in 3GPP and the Simulation in COSSAP

介绍了第三代移动通信无线传输技术的进展情况 ,着重介绍了其算法结构中的信道结构、信道编码、复接和多址技术 ,以及这些技术在高性能仿真软件COSSAP中的仿真实现。最后 ,给出了第三代移动通信UMTS系统的下行链路的仿真例子 ,及如何用COSSAP实现从算法到硬件的方法 .

In this paper,introduce the evolution of radio transmission technology (RTT) of the 3rd generation mobile communication,then emphasis on the explanation of frame structure,channel coding,multiplexing,and multiple access technologies of 3G RTT,also the simulation of these technologies in COSSAP is explained. Finally,present an example of UMTS downlink simulation in COSSAP,and bring forward a methodology that bridges the gap between algorithm and hardware implementation using COSSAP.
