A Simulation Platform for WCDMA Digital Baseband Algorithm Evaluation

研究了适用于第三代移动通信系统的DS-CDMA链路的基带算法软件仿真平台。在WCDMA系统的设计中可以选择多种高级信号处理算法与运行环境,仿真平台的设计是为了进行基带处理算法如信道估计、多用户检测和空-时联合处理等算法的开发、仿真与评估,从而对系统设计进行指导。基本的链路仿真平台建立在Matlab基础上。文中还讨论了优化仿真模型,提高仿真速度的方法。

This paper describes a software platform which simulates a DS-CDMA link for the 3rd generation mobile communication system. We can choose wide array of advanced signal processing algorithms and a variety of operating environments in WCDMA system design. The goal of such simulator is to develop, simulate and evaluate the baseband processing algorithms like channel estimation, multiuser detection and space-time joint processing, etc. This could be a guidance for system design. The backbone of this platform is built using Matlab. Efficient methods to optimize and accelerate the simulation are also discussed.
