Abstract

To address the spectrum scarcity problem and enhance spectrum utilization efficiency, spectrum sharing and coexistence of different wireless communication systems are important ongoing research topics. Unlicensed use of the ISM band by the long-term evolution (LTE) wireless cellular system is expected to bring large performance enhancement to users of LTE, but its coexistence with incumbent Wi-Fi users must be carefully considered. In this paper, we implement a simulation-based study to investigate the effect of LTE interference on an IEEE 802.11a system, in terms of physical-layer packet error rate (PER) and throughput. Simulation results show that considered LTE interference waveform generates colored-noise like effect on Wi-Fi receivers, and is less harmful on Wi-Fi detection performance than full-band white noise given the same power.
