Frequency Interleaved Modulators to Support Channel Bonding in Satellite Communications

Next generation wireless communication systems such as high throughput satellites and fifth generation mobile communications have promised a step increase in the rate at which data can be transmitted. This would ideally require bespoke modulator designs for the ground stations with wide bandwidths employing expensive high throughput data converters. The next generation communications hardware also need to be backward compatible with legacy systems of lower bandwidths till they are rendered obsolete. In this paper we demonstrate a scheme to generate a wide bandwidth modulated baseband signal with multiple modulators of narrower bandwidths in a satellite communications ground station
