Abstract The paper investigates the effect of including the turbo coding in the 3G system . The bit error rate performance of the system with AWGN channel is investigated to study the effect of number of iteration , frame size , code rate and memory size of the symmetrical convolutional code . It then assess the performance of the system over mobile fading channel that exhibits Rayleigh multipath . The assessment also compares the performance with and without diversity . This paper also investigates the effect of turbo code with diversity on reverse link capacity to find the maximal number of simultaneous users per cell . The results of computer simulation clearly demonstrate the magnificent enhancement gained by the use of turbo coding on the performance of the system ( bit error rate ) . Furthermore , it has been found that as the iteration number and frame size increase the advantages in tolerance to additive white Gaussian noise will also increases .
