PERFORMANCE EVALUATION OF TURBO CODE ENDCODING AND DECODING

Author

Abstract
Channel coding is very important for secure communication. The most widely used communication coding is turbo coding technique, which is very secure technique. We deal in this paper with turbo code which is new class of convolutional codes. The performance of turbo code reaches the Shanon limits in terms of bit error rate BER. To build the turbo code encoder we used two parallel concatinations of two Recursive Systematic Convolutional codes (RSC) and the associated decoder which is using the feedback decoding rule. At low signal-to-noise ratio (SNR), bit error rates (BER) of Turbo code were obtained by simulation.
