【Abstract】 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.更多还原
