Efficient Computation of EXIT Functions for Nonbinary Iterative Decoding

Kliewer, Jorg, Ng, S.X and Hanzo, L (2006) Efficient Computation of EXIT Functions for Nonbinary Iterative Decoding IEEE Transactions on Communications, 54, (12), pp. 2133-2136.

Record type: Article


The calculation of nonbinary extrinsic information transfer charts for the iterative decoding of concatenated index-based codes is addressed. We show that the extrinsic information at the output of a constituent a posteriori probability decoder can be calculated with very low complexity, where expensive histogram measurements are not required anymore. An example for turbo trellis-coded modulation demonstrates the capabilities of the proposed approach.
