Unequal error protection for convolutional codes

Pavlushkov, Victor LU ; Johannesson, Rolf LU and Zyablov, VV (2006) In IEEE Transactions on Information Theory 52(2). p.700-708
Abstract
In this correspondence, unequal error-correcting capabilities of convolutional codes are studied. For errors in the information symbols and code symbols, the free input- and output-distances, respectively, serve as '' unequal '' counterparts to the free distance. When communication takes place close to or above the channel capacity the error bursts tend to be long and the free distance is not any longer useful as the measure of the error correcting capability. Thus, the active burst distance for a given output and the active burst distance for a given input are introduced as '' unequal '' counterparts to the active burst distance and improved estimates of the unequal error-correcting capabilities of convolutional codes are obtained and...

In this correspondence, unequal error-correcting capabilities of convolutional codes are studied.

Thus, the active burst distance for a given output and the active burst distance for a given input are introduced as '' unequal '' counterparts to the active burst distance and improved estimates of the unequal error-correcting capabilities of convolutional codes are obtained and illustrated by examples. Finally, it is shown how to obtain unequal error protection for both information and code symbols using woven convolutional codes. (Less)
