Convolutional Interleaver for Unequal Error Protection of Turbo Codes
This paper describes construction of a convolutional interleaver as a block interleaver and discusses its application to turbo codes with equal and unequal error protection techniques. Based on simulations, different convolutional interleaver structures suitable for turbo codes with unequal error protection capability are suggested. Finally, based on conducted simulations the best method is sel...
متن کاملPaper Application of convolutional interleavers in turbo codes with unequal error protection
This paper deals with an application of convolutional interleavers in unequal error protection (UEP) turbo codes. The constructed convolutional interleavers act as block interleavers by inserting a number of stuff bits into the interleaver memories at the end of each data block. Based on the properties of this interleaver, three different models of UEP turbo codes are suggested. Simulation resu...
متن کاملApplication of Unequal Two–fold Turbo Codes to Hsl Image Transmission
Besides their excellent error performance, multi fold turbo codes [1], [2] are attractive options for transmitting multimedia data due to their scalable structure in terms of variable coding frequency and code length. This article introduces a novel unequal error protection scheme that is based on the least complex member of multifold turbo codes, ie two-fold turbo codes, and its application to...
متن کاملJoint Source-Channel Coding with Unequal Error Protection using Asymmetric Turbo Codes
In this paper, we devise an efficient joint source-channel coding scheme for robust image transmission over noisy channels. We firstly present a novel interleaver, named unequal row column cyclic cross interleaver, which could improve the error correction capability of turbo codes effectively. Secondly, we devise two types of asymmetric turbo codes which consist of the parallel concatenated tur...
متن کاملTurbo Unequal Error Protection Codes with Multiple Protection Levels
Most existing Turbo unequal error protection (UEP) codes provide two error protection levels at the cost of extending the block size of the codeword or increasing the computational complexity. This paper proposes two novel Turbo UEP coding schemes, which provide multiple error protection levels for information bits, according to their different sensitivities to the channel noise. By permuting t...
