Design of RF Control System Based on TD-LTE

Abstract:

This paper explains a method to design a RF system using FPGA and DSP. After DSP sending RF circuit controlling words to FPGA through its EMIF interface, FPGA then imitate the behavior of the EMIF interface to receive these information. The received data will be used to configure the RF circuit correctly. Data information will be sent to FPGA in the same way by DSP when RF circuit is configured completely, Then FPGA sends baseband data to RF circuit which convert it to RF signal. Through simulation, synthesis, plate level verification, and online debugging, this design has realized the correct RF control system, which has been used in the development of RF conformance test instruments.
