Turbo code has become the coding technique of choice in many communication and storage systems due to its near Shannon limit error correction capability. With requirement on increasing data rates for deep space mission, it is required to have efficient encoder and decoder. Turbo codes provide up to 0.8 dB improvement in Eb/No over the current best codes used by deep space missions. The total number of decoder iterations depends on the physical channel characteristics. In this paper, we proposed a turbo encoder with the 1/3,1/4,1/6 rate and turbo decoder.
