Abstract
This paper presents a recent result of the study on efficient 3GPP compliant method to simulate multiple independent multipath fading radio channels in multi-UE (User Equipment) software defined Evolved Universal Terrestrial Radio Access Network (E-UTRAN) traffic generator. In the previous research Ill, authors discussed Digital Fourier Transform (DFT) based frequency domain simulation models of a multipath fading channel, including aspects of terminal mobility and Intercarrier Interference (ICI). In this paper, previously published simulation results, showing accuracy and efficiency of the models, are confirmed using mathematical analysis of ICI phenomenon, considering nature of Orthogonal Frequency Division Multiple Access (OFDMA) schemes adapted by the 3GPP Long Term Evolution (LTE) standard. Complexity of frequency domain models is evaluated in detail using Big Onotation and compared against time domain approach. The research shows that direct frequency domain linear ICI approximation, represented by the frequency domain model 2, offers good accuracy in term of ICI synthesis for the most practical Doppler frequencies and simultaneously requires less operations if the number of simulated UEs is large.
