The effect of constraint length and interleaver on the performance of turbo code

Abstract EN

This paper presents a class derived from convolutional code called turbo code.

The performance of turbo code is investigated through examining the effect of different constraint length, the effect of changing rate, and the effect of interleaver on the performance of turbo code with presence burst errors.

The performance of turbo code is investigates through computer simulation, by using MATLAB program.

The simulation encoder is composed of two identical RSC component encoder with parallel concatenated, separated by interleaver.The turbo code simulation results are shown graphically for different constraint length, in hard and soft decision.

Also the simulation results are shown for case with interleaver and without interleaver.
