Design and Implementation of Baseband Processing Platform for Mobile-Digital Signals

LI Xiao-we

Abstract

A baseband processing platform for mobile-digital signals in TD-LTE system was designed based on multiprocessor including ARM,DSP and FPGA.Baseband signal in mobile communication could be processed limberly on this platform,whose major functional modules include protocol software implementation,physical layer algorithms and system timing.Tests were performed on the platform,and results showed that,in LTE mode and 20MHz bandwidth,the platform was in accordance with standard LTE specification,and its real-time performance and effectiveness were demonstrated.With excellent versatility,the baseband processing platform also met requirements of TD-SCDMA,WCDMA,CDMA2000and other wireless communication systems for digital signal processing.
