Lossy Joint Source-Channel Coding Using Raptor Codes

<table>Conceptual block diagram of the
conventional SSCC and the proposed JSCC schemes. The two schemes coincide but
for the fact that the concatenation of entropy coding and channel coding (SSCC)
is replaced by a single linear encoding block (JSCC).</table>
