| Summary: | allotting as much of available channel redundancy to them as based on their susceptibility to channel errors. Errors in be an useful method for separating input into bit streams of bits into 4-PSK symbols for transmission over an AWGN bits. A subband coder is designed to provide encoded bits bits. Errors in the less important bits caused a very small channel. The individual performances of the subband coder and coders, each with a different level of error protection for important bits should be given a preferential treatment by increase in the overall distortion. This implied that the is studied. The distortion in the reconstructed signal at of the channel coders is simulated as a coded modulation possible. Protection scheme for selectively protecting subband coded reconstructed signal. This thesis presents an Unequal Error scheme with an underlying convolutional code to map coded Source coded data can be separated into different classes source of the first order is used as the source model. system consisting of the subband coder and the channel coder the channel coder are presented. Subband coding is shown to the different classes of output from the subband coder. Each the Important bits cause greater distortion in the the receiver was more when there were errors in the important Unequal error protection is provided by a bank of channel varying levels of importance.
