APPARATUS FOR ANALYSIS/VERIFICATION OF DIGITAL SIGNAL IN OFDM-MIMO BASE TRANSCEIVER SYSTEM

摘要

An apparatus for digital signal analysis/verification in an OFDM-MIMO base station is provided to temporarily store baseband signals of the base station in a buffer in real time to easily grasp an operation state of the OFDM-MIMO base station system and transmit the baseband signals to an external PC, thereby first analyzing a digital signal of the OFDM-MIMO base station system in real time. An apparatus for digital signal analysis/verification in an OFDM-MIMO(Orthogonal Frequency Division Multiplexing-Multi Input Multi Output) base station comprises the followings: a mother board(110) which receives LVDS(Low Voltage Differential Signal) data from a BPPU(Baseband PHY Processing Unit) performing a modem function in an MIMO channel card and stores it in a memory(115); and a daughter board(120) which transmits the data, stored in the memory(115), to an external PC(Personal Computer)(200) through a TCP/IP(Transmission Control Protocol/Internet Protocol) and makes the external PC(200) perform the digital signal verification of the OFDM-MIMO base station.
