A turbo-coded hybrid ARQ for low earth orbit microsatellite communications

摘要

A proposed turbo-coded hybrid ARQ designed for improving the throughput of UoSAT/SSTL LEO microsatellite downlink communications is presented. The flexibility and robust error correcting capability of turbo codes are incorporated adaptively into the existing ARQ protocol. The proposed scheme optimizes the increment of coding parity and schedules the decoding iterations to take place during intervals between microsatellite passes.
