Research abstract
To meet the requirements for AF171_041, "Next Generation Satellite Transponder using Low-Cost Adaptive HPA Linearization Technologies," MaXentric proposes a solution that essentially utilizes the existing satellite hardware to implement adaptive bandlimited digital pre-distortion (DPD). The pre-distortion will work within the bandwidths of the existing hardware and does not require any new ADCs/DACs.This offers a significant advantage as space-qualified ADC/DACs lag in performance to the latest state of the art in terms of resolution, as well as the sampling rate. To overcome the resolution and sampling rate limitation, we are proposing a band-limited real-time predistortion system, reducing the required sampling rate by more than 2 times compared to conventional DPD systems.The Phase 1 work will simulate an adaptive bandlimited DPD system for a satellite SSPA/TWT system including multicarriers and jammers and show its benefits. The phase 2 work will demonstrate the prototype system.
