Abstract

Channel emulators are usually used to evaluate preliminary performances of the newly developed wireless algorithms in the laboratory without resorting to the on-site measurements which are generally complex and costly. In this study, a simple but effective channel emulator that features a benchtop-sized (small-sized) reverberation chamber (RVC), radio frequency (RF) cable, and power controller is proposed for emulating a Rician propagation environment with a flexibly controllable k-factor. The developed emulator has the ability to precisely introduce the Rician propagation effect (with the desired k-factor) to the input RF signal. The performance of the proposed emulator was evaluated through measurement and its accuracy was validated by conducting a Kolmogorov-Smirnov (KS) goodness-of-fit (GoF) test. The emulator is suitable for both algorithm/prototype testing and educational purpose in wireless laboratories.
