Interleaver design for short block length Turbo codes
نویسنده
چکیده
The performance of a Turbo code depends on the interleaver design. There are two major criteria that can be considered in the design of an interleaver. Distance spectrum properties of the code and the correlation of the extrinsic information with the input data are the two major criteria in designing an interleaver. This paper describes a new interleaver design based on these two criteria. Simulation results compare the new interleaver design to different existing interleavers. The distance spectrum properties of the Turbo code are compared for different interleaver choices. A new solution to the interleaver edge effects is

Interleaver design for turbo codes
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 b...
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 کاملMatched Interleavers for Turbo Codes With Short Frames
The selection of the interleaver has a major influence on the performance of turbo codes with short frames. In this paper, block interleavers are considered. The best block interleaver matched to a given turbo code is obtained by determining the number of columns of the interleaver that will provide the largest effective free distance. It will be shown that at high signal-to-noise ratios a bloc...
متن کاملOn 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 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...
