摘要
本文提出了一种用于TD-LTE BTS收发系统的紧凑型2×2 MIMO模拟基带处理单元。设计的系统支持两个独立的发射器和接收器。通过光纤或局域网电缆在基带和数字基带子系统之间进行数据传输，既灵活又方便。板载FPGA支持CPRI (Common Public Radio Interface)和GE (Gigabit Ethernet)接口。它也可以用于一些数据处理，如校准，数字预失真(DPD)等。在19.2MHz 16QAM信号和20MHz TD-LTE信号下的EVM测量结果分别为0.45%rms和1.29%rms，验证了基带板的优良性能。设计的2×2紧凑型MIMO模拟基带处理单元将射频板、电源板和控制器集成在一起，成功地在TD-LTE试验网络中实现。
Design of a FPGA-based baseband for MIMO TD-LTE BTS
A compact 2×2 MIMO analog baseband processing unit for the TD-LTE BTS transceiver system is presented in this paper. The designed system supports two independent transmitter and receiver. Data can be transmitted between the baseband and the digital baseband subsystem flexibly and conveniently by either the optical fibers or the LAN cable. The on-board FPGA can support the Common Public Radio Interface (CPRI) and the Gigabit Ethernet (GE) interface. It can also be used for some data processing such as the calibration, digital predistortion (DPD), etc. Measurement results of EVM with a 19.2MHz 16QAM signal and a 20MHz TD-LTE signal are 0.45%rms and 1.29%rms respectively, which verifies excellent performance of the baseband board. With RF board as well as power and controller board integrated together, the designed 2×2 compact MIMO analog baseband processing unit is implemented in the TD-LTE trial network successfully.
