What's the difference between turbo codes and traditional concatenated codes?

Implementation of Turbo coding and decoding in MIMO system and research on Turbo concatenated space-time codes: MIMO technology is an important way to realize high data rate and improve transmission quality in the third generation and future mobile communication and personal communication systems. As a verification system for MIMO algorithm performance verification, it is an important step in MIMO technology research. This paper first introduces the MIMO experimental verification system to be developed in the project, and then gives the Turbo code encoder and decoder used in MIMO system.
