SCCC Turbo Equalizer/Decoder for X-band Nano Satellite High-Speed Downlink System

Abstract

To provide data rate more than 100 Mbps for nano satellite communications, we have developed an X-band downlink system with a modulation symbol rate of 100 Msps. The received signals of nano satellites tend to suffer much more distortion due to the transmitter and channel constraints. Several effective techniques based on turbo equalizer/decoder have been developed and verified via computer simulation therefore, the obtained results apply to the downlink system design.
