Abstract
The Turbo coding ingeniously combine two simple component coders, use pseudo random interleaver parallelly to construct long code which obtains random characteristic , and take advantage of iterations between the two input/output (SISO)[1,2] decoder to realize pseudorandom decoding. This paper introduces encoding and decoding principle, design and simulation performance of Turbo codes. The simulation results prove that the design scheme is correct. From the spectral character we are acknowledged: not only can Turbo code effectively against the Gauss noise, but also has strong resistance to fading and interference properties. Based on our resuls, the Turbo code in modern communication has more advantages and will play more important role.
