Test Platform of LTE-U Communication System Based on FPGA

In order to solve the problem that the LTE communication system cannot be easily deployed, we design a test platform of LTE-U communication system based on FPGA. The test platform includes mobile terminals, base stations and base station networking system. It supports 5G unauthorized frequency band, WIFI and 100M network. A single base station can support up to 8 terminals with a distance of 1 km. It uses an omnidirectional antenna to communicate with the terminal and uses a gigabit ring network between base stations. In the process of mobile communication, we use RSSI (received signal strength indication) and bit error rate as the evaluation criteria and test the 32 terminals covered by the chain network and 4 base stations. The test platform can complete the LTE-U test well.
