Abstract

In order to realize the flexible construction and performance test of 4G communication system, in this paper, using the GPP (General Purpose Processor) and USRP as the hardware platform of Software Defined Radio (SDR), based on the open source srsRAN software platform, the 4G communication link is built which realizes UE accessing the Internet. Firstly, the peak rate of the system based on the RE algorithm is studied, and the influencing factors of the peak rate are analyzed. Secondly, the uplink and downlink peak rate of the 4G link is measured by the two transmission modes of antenna and coaxial cable respectively. After comparative analysis, it can be concluded that the transmission mode of coaxial cable is more stable and the SNR (Signal to Noise Ratio) is better. At the same time, it verifies that CPU performance affects uplink and downlink peak rates, and that adjusting the RF (Radio Frequency) gain can achieve the maximum throughput which is also consistent with the theoretical value of peak rates.
