Co-channel Interference for Terrestrial and HAPS Systems in a Cellular Structure

In this paper, the effects of co-channel interference in a HAPS-based cellular system are analysed, comparing such effects in two frequency reuse scenarios with terrestrial systems. The CIR is evaluated for both schemes, and the HAPS-based cellular system shows significant improvements in the reduction of co-channel interference over terrestrial systems, even when compared to sectorised configurations.
