Description

This paper analyses the bottlenecks of receiverschemes utilized in transponders for space communications con-sidering new operation scenarios, the potential gains introducedby more powerful coding schemes, and the advances on newtransponder architectures. The paper focuses on the synchroniza-tion stages, where traditional closed-loop architectures are stillused in current transponders for deep space communications.The performance analysis, based on thorough simulation results,identifies bottlenecks on operational modes for current CCSDSstandards. The work also identifies enhancements to state-of-the-art receiver techniques that can bring significant gains intoperformance limits.
