Abstract

Turbo decoding for 3GPP-LTE wireless communication standard is most challenging task to reduce computational complexity. The complexity of Turbo decoder is much higher than the complexity of Turbo encoder. Turbo decoder complexity depends on decoding algorithm. Less complexity in decoding gives degraded performance. Turbo decoder performance also depends on the number of iterations used during decoding. This paper describes different types of iterative Turbo decoding algorithm. The correction factor, how it deviates in different algorithms is discussed. BER analysis is done for different Turbo decoding algorithms. The effect of number of iterations for Max-Log-MAP decoding is shown using MATLAB simulation.
