Coded transmissions for space links affected by solar scintillation: Baseband analysis

Abstract

SummaryA thorough analysis of the behavior of error‐correcting codes over space links affected by solar scintillation is presented. The relevant channel parameters are fixed through the development of a model based on real missions' data. Both telecommand and telemetry links are considered in fast and slow fading conditions. Besides classical coherent modulation schemes, the possibility to use noncoherent modulation schemes is considered, to eliminate the problem of phase tracking. For the case of channels with very slow fading, the use of external interleavers or erasure coding is proposed to cope with error bursts.

Validation of a software‐defined baseband system for satellite telemetry and telecommand

“…In this work, we do not take into account the validation of Turbo codes. This can be found in Baldi et al 11 and Andrews et al 13 . Finally, we show that the SDB is capable of operating in a realistic TM/TC scenario by communicating with three different orbiting satellites.…”

“…Both scenarios assumed perfect synchronization. The continuation work by Baldi et al 11 presented the performance of TM/TC links in a channel with solar scintillations. This work also assumed perfect synchronization.…”
