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 …

The principle of turbo codes has been analyzed in this paper, and a new unequal error
protection turbo codes by designing a new puncturing scheme are proposed. The …

In this paper, the Turbo-based unequal protection mechanism for reliable transmission of
speech signal is studied. In order to obtain the hierarchical importance regularity of …

A novel Turbo Unequal Error Protection (UEP) coding scheme is proposed in this paper. In
our scheme, two error protection levels of Turbo codes are achieved by a new rate …

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 …

An investigation of unequal error protection (UEP) methods applied to JPEG image
transmission using turbo codes is presented. The JPEG image is partitioned into two groups …

In many communications systems, data can be divided into different importance levels. For
these systems, unequal error protection (UEP) techniques are used to guarantee lower BER …

Examining the Bit Error Rate (BER) at various positions of a Turbo Coded data block reveals
that Turbo Codes inherently possess Unequal Error Protection (UEP) properties. In this …

For some applications in communications, it is desirable to provide unequal error protection
for different types of information data. In image coding, eg, types of bits exist which have to …
