Abstract

Inspired by the modular design of virtual instruments, a discrete non-stationary channel model and a flexible hardware architecture are proposed in this paper. On this basis, a universal channel emulator is implemented on universal software radio peripheral (USRP) platform. Moreover, we proposed a sum of linear frequency modulation (SoLFM) method to accurately generate non-stationary channel fading with continuous phase, i.e., Rayleigh fading, Rice fading, and log-normal fading channels. In addition, hardware measurement results demonstrate that the measured statistical properties are well consistent with the corresponding theoretical ones.
