Interleaver design for turbo codes
نویسندگان
چکیده
The performance of a Turbo code with short block length depends critically on the interleaver design. There are two major criteria in the design of an interleaver: the distance spectrum of the code and the correlation between the information input data and the soft output of each decoder corresponding to its parity bits. This paper describes a new interleaver design for Turbo codes with short block length based on these two criteria. A deterministic interleaver suitable for Turbo codes is also described. Simulation results compare the new interleaver design to different existing interleavers.

On the Design and Performance of high throughput parallel block and random interleavers for Turbo Codes
It is known that one of the essential building blocks of turbo codes is the interleaver and its design using random, semi-random (S-Random) and deterministic permutations. In this paper, two new types of turbo code interleavers, Enhanced Block S-Random (EBSR) interleaver is proposed. The design algorithm for the new interleaver is described in depth, and the simulation results are compared to t...
متن کاملA New Deterministic Interleaver for Turbo Codes
Interleavers play a critical role in performance of turbo codes. The turbo code performance curve can change its slope in low bit error rate (BER) region, if the interleaver is not designed properly. The interleaver is also a cause of bottleneck for parallelization of turbo decoder. In this paper, we propose the design of interleaver that combines the regular permutation of the interleaver and ...
متن کاملOn Design of Interleavers with Practical Size for Turbo Codes
In this paper, we propose a new method to design an interleaver with practical size for turbo codes. In order to construct an optimal interleaver, we first set up the following design rules: (i) to suppress the interleaver correlation; (ii) to break up self-terminating weight-2 input sequences; and (iii) to avoid edge effects. We then synthesize a new type of interleaver structure, starting wit...
متن کاملCombined turbo codes and interleaver design
In this letter the impact of the distance spectrum and interleaver structure on the bit error probability of turbo codes is considered. A new turbo code design method for Gaussian channels is presented. The proposed method combines a search for good component codes with interleaver design. The optimal distance spectrum is used as the design criterion to construct good turbo component codes at l...
متن کاملSuccessive packing based interleaver design for turbo codes
Interleaver design plays an important role to improve the performance of turbo codes. The optimal performance can be obtained by using pseudo-random interleaver design. However, it is difficult to analyze the corresponding pseudorandom algorithms such that the performance can be guranteed, and furthermore they are computational expensive. In this paper, we focus on deterministic turbo codes int...
