Iterative source-channel decoding using soft-in/soft-out decoders
The concept of iterative decoding of concatenated channel codes is applied to joint source-channel decoding (JSCD). Extrinsic information from the soft-in/soft-out channel decoder is used as a priori information for the new soft-in/soft-out source decoder and vice versa. In this novel iterative approach the redundancies within the data-bits and the channel codewords are alternately exploited in order to approximate the highly complex optimal JSCD.
