The Effect Of Constraint Length And Interleaver On The Performance Of Turbo Code


This paper presents a class derived from convolutional code called turbo code. Theperformance of turbo code is investigated through examining the effect of different constraintlength, the effect of changing rate, and the effect of interleaver on the performance of turbocode with presence burst errors.The performance of turbo code is investigates through computer simulation, by usingMATLAB program.The simulation encoder is composed of two identical RSC component encoder with parallelconcatenated, separated by interleaver.The turbo code simulation results are showngraphically for different constraint length, in hard and soft decision. Also the simulationresults are shown for case with interleaver and without interleaver.
