Abstract [en]

In this paper, we study the design of a causal anytime encoding and decoding scheme for transmission of real-time information over a binary symmetric channel. In particular, our scheme combines unequal-error protection (UEP) rateless codes with sequential belief propagation decoding. In order to minimize delay in decoding and reduce distortion, we formulate and solve a linear programming problem. Moreover, degree distributions of the UEP-rateless codes are optimized since the efficiency of rateless codes highly depends on the corresponding degree distribution. The performance of the proposed scheme is demonstrated by using numerical simulations, and will be compared with an existing work.
