Abstract
The error correcting capability of the unequal error protecting (UEP) Codes is described in terms of correcting errors in specific digits of a codeword even though other digits may be decoded incorrectly. We investigate the overall distortion when these codes are applied to transmission of analog sources in a communication system. Simulation and analytic results indicate the performance improvement gained by using UEP codes for various sources and source encoding structures.<>
