The principle of encoding and decoding for Turbo code and the Log-MAP decoding algorithm are introduced. The encoding and decoding processes are implemented on the Altera DE4 development board and the parameters of the encoder and decoder are based on the 3GPP Long Term Evolution(LTE) standard，which can work with any code length in LTE physical link. Finally，a simulation platform is built. The data from hardware implementation and simulation are compared to verify the feasibility of this implementation.
