Co-Existence Analysis of LTE and WiMAX in Uplink

In this paper, the intra system and inter system interference model is studied when LTE and WiMAX coexist. A static system level simulator is used to investigate the capacity loss in case of co-existence of macro LTE uplink and macro WiMAX uplink. The capacity loss under different frequency spacing or adjacent channel interference ratios (ACIRs) and different sites offset is obtained. It is shown that the co-site case has better uplink system performance with less capacity loss and when ACIR offset is above 20 dB the two systems will have neglectable impact on each other.
