چکیده

Turbo coding is the most commonly used error correcting scheme in wireless systems resulting in maximum coding gain. In this paper, a comparative study of the symbol-bysymbol maximum a posteriori (MAP) algorithm, its logarithmic versions, namely, Log-MAP and Max-Log-MAP decoding algorithms used in SISO Turbo Decoders are analyzed. The performance of Turbo coding algorithms are carried out in terms of bit error rate (BER) by varying parameters such as Frame size, number of iterations and choice of interleaver. Keywords-: Iterative decoding; MAP decoding; Turbo Codes.

Comdined Turbo Block Decoding and Equalisation

In this paper, the combination of equalization and turbo decoding is studied. In the iterative decoding of a product code in block turbo coding system, the equalization process is performed within the iteration loop. The present study aims to investigate the decision feedback equalizer (DFE) incorporated in the iterative decoding. Simulation results show that the more severe the channel interfe...

Low Complexity Turbo Decoders for Noncoherent FH/SS over Partial Band Jammed Channel

In this study, turbo codes were investigated in a slow frequency-hopped binary frequency shift keying spread spectrum (FH/BFSK-SS) system with partial band jamming and full-band thermal noise. A soft decision decoding metric which includes automatic gain control (AGC) is proposed for turbo code decoding with a non-coherent square law receiver of FH/BFSK. The study focused on the performance com...

Codes and Decoding on General Graphs

Iterative decoding techniques have become a viable alternative for constructing high performance coding systems. In particular, the recent success of turbo codes indicates that performance close to the Shannon limit may be achieved. In this thesis, it is showed that many iterative decoding algorithms are special cases of two generic algorithms, the min-sum and sum-product algorithms, which also...
