Abstract
Next generation networks will have to provide global connectivity to ensure success. Both satellite and terrestrial networks cannot guarantee this on their own. This incapability is attributed to capacity coverage issues in densely populated areas for satellites and lack of infrastructure in rural areas for terrestrial networks. Therefore, we consider a hybrid terrestrial-satellite mobile system based on frequency reuse. However, this frequency reuse introduces severe co-channel interference (CCI) at the satellite end. To mitigate CCI, we propose an OFDM based adaptive beamformer implemented on-board the satellite with pilot reallocation at the transmitter side. Results show that the proposed scheme outperforms the conventional approach.
