SECOND HARMONIC MEASUREMENT DEVICE OF INTEGRATED FIBER REPEATER SYSTEM

摘要

PURPOSE: A device for measuring the second harmonic signal of an integrated optical repeater is provided to quantitatively and qualitatively measure the status of reverse direction code division multiple access (CDMA) signal interference by using a field-programmable gate array (FPGA) installed at the integrated optical repeater when attempting/connecting a call of long term evolution (LTE) data. CONSTITUTION: An FPGA (210) has a signal generator and a signal detector. A fourth generation (4G) transmission signal processing part (221) is connected to the signal generator of the FPGA. A multiplexer (230) is connected to the 4G transmission signal processing part. An antenna (240) is connected to the multiplexer. A second generation (2G) received signal processing part is connected between the multiplexer and the signal detector of the FPGA. [Reference numerals] (211) Signal generator; (212) Signal detector
