摘　　要：设计了基于ARM,DSP和FPGA多处理器的分时长期演进系统(TD-LTE)移动数字信号基带处理平台。该处理平台能够灵活实现移动通信中基带信号的各种操作,主要功能模块包括协议软件实现、物理层算法实现、系统定时等。经测试,在LTE模式及20MHz带宽下,平台符合LTE标准技术指标要求,验证了其实时性、高效性。另外,该基带处理平台从硬件设计上还满足TD-SCDMA,WCDMA,CDMA2000等各种无线通信系统的数字信号处理需求,只需适当修改部分软件,即可实现多种制式的基带处理功能,具有良好的通用性。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 coutd 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 20 MHz 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, CDMA2000 and other wireless communication systems for digital signal processing.
