Abstract
The hardware-in-the-loop (HIL) simulation is an advanced simulation method. It overcomes the weakness of bad reliability and lower efficiency in traditional pure computer simulation method, by the combination of simulation computers and field equipments. Meanwhile, the communication quality in high-speed environment has become a shared concern of related researchers, with the wireless communication system working in higher frequency and broader bandwidth. In this paper, we build our HIL simulation system with the software-defined radio platform and a radio channel emulator. And then we analyse the RF performance of LTE uplink received signal in the conditions of different mobile speed and SNR. Finally, we get the conclusion that mobile speed has an important effect on EVM, and affects ACLR, OBW, and SEM obviously, but has little influence on IQ quadrature skew, IQ offset, and IQ gain imbalance. While SNR affects all the parameters.
