Multiple description analog joint source-channel coding for parallel channels with side information

With the purpose of reducing the coding complexity and delay of the separation-based schemes, an analog joint source-channel coding scheme is proposed for transmissions through parallel AWGN channels with side information at the receiver. This scheme divides the bidimensional source space into a set of hexagons and transmits the relative position of the source vectors inside the corresponding hexagon by using two complimentary analog mappings. The results are satisfactory, specially taking into consideration the low complexity and delay of the proposed scheme.
