Abstract :
An extended analog joint source-channel coding (JSCC) multiple description (MD) scheme is introduced. This new scheme extends a previously presented analog JSCC-MD scheme in order to work at different bandwidth ratios. This scheme is suitable for transmissions through parallel AWGN on-off channels and parallel slow-fading channels. The strengths of the proposed scheme in comparison with other coding alternatives are its coding/decoding simplicity and low delay, and its optimality in terms of distortion exponent in the fading parallel channels.
