Transmission of analog sources using unequal error protecting codes

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. >
